Contents of long symlinks is written via standard write methods. So
when the write fails, we add inode to orphan list. But symlinks don't
have .truncate method defined so nobody properly removes them from the
on disk orphan list.
Fix this by calling ext4_truncate() directly instead of calling
vmtruncate() (which is saner anyway since we don't need anything
vmtruncate() does except from calling .truncate in these paths). We
also add inode to orphan list only if ext4_can_truncate() is true
(currently, it can be false for symlinks when there are no blocks
allocated) - otherwise orphan list processing will complain and
ext4_truncate() will not remove inode from on-disk orphan list.

The following race can happen:
CPU1 CPU2
checkpointing code checks the buffer, adds
it to an array for writeback
do_get_write_access()
...
lock_buffer()
unlock_buffer()
flush_batch() submits the buffer for IO
__jbd2_journal_file_buffer()
So a buffer under writeout is returned from
do_get_write_access(). Since the filesystem code relies on the fact
that journaled buffers cannot be written out, it does not take the
buffer lock and so it can modify buffer while it is under
writeout. That can lead to a filesystem corruption if we crash at the
right moment.
We fix the problem by clearing the buffer dirty bit under buffer_lock
even if the buffer is on BJ_None list. Actually, we clear the dirty
bit regardless the list the buffer is in and warn about the fact if
the buffer is already journalled.
Thanks for spotting the problem goes to dingdinghua <dingdinghua85@gmail.com>.

The ext4 module uses rcu_call() thus it should use rcu_barrier()on
module unload.
The kmem cache ext4_pspace_cachep is sometimes free'ed using
call_rcu() callbacks. Thus, we must wait for completion of call_rcu()
before doing kmem_cache_destroy().

As Ted noted, the ext4_allocation_request isn't well aligned. Looking
at it with pahole we're wasting space on 64-bit arches:
struct ext4_allocation_request {
struct inode * inode; /* 0 8 */
ext4_lblk_t logical; /* 8 4 */
/* XXX 4 bytes hole, try to pack */
ext4_fsblk_t goal; /* 16 8 */
ext4_lblk_t lleft; /* 24 4 */
/* XXX 4 bytes hole, try to pack */
ext4_fsblk_t pleft; /* 32 8 */
ext4_lblk_t lright; /* 40 4 */
/* XXX 4 bytes hole, try to pack */
ext4_fsblk_t pright; /* 48 8 */
unsigned int len; /* 56 4 */
unsigned int flags; /* 60 4 */
/* --- cacheline 1 boundary (64 bytes) --- */
/* size: 64, cachelines: 1, members: 9 */
/* sum members: 52, holes: 3, sum holes: 12 */
};
Grouping 32-bit members together closes these holes and shrinks the
structure by 12 bytes. which is important since ext4 can get on the
hairy edge of stack overruns.

Ted noticed a stack-deep callchain through
writepages->ext4_mb_regular_allocator->ext4_mb_init_cache->submit_bh ...
With all the static functions in mballoc.c, gcc helpfully
inlines for us, and we get something like this:
ext4_mb_regular_allocator (232 bytes stack)
ext4_mb_init_cache (232 bytes stack)
submit_bh (starts 464 deeper)
the 2 ext4 functions here get several others inlined; by telling
gcc not to inline them, we can save stack space for when we
head off into submit_bh land and associated block layer callchains.
The following noinlined functions are only called once, so this
won't impact any other callchains:
ext4_mb_regular_allocator (104) (was 232)
ext4_mb_find_by_goal (56) (noinlined)
ext4_mb_init_group (24) (noinlined)
ext4_mb_init_cache (136) (was 232)
ext4_mb_generate_buddy (88) (noinlined)
ext4_mb_generate_from_pa (40) (noinlined)
submit_bh
ext4_mb_simple_scan_group (24) (noinlined)
ext4_mb_scan_aligned (56) (noinlined)
ext4_mb_complex_scan_group (40) (noinlined)
ext4_mb_try_best_found (24) (noinlined)
now when we head off into submit_bh() we're only 264 bytes deeper
in stack than when we entered ext4_mb_regular_allocator()
(vs. 464 bytes before). Every 200 bytes helps. :)

The ext4_block_truncate_page() function previously called
grab_cache_page(), which called find_or_create_page() with the
__GFP_FS flag potentially set. This could cause a deadlock if the
system is low on memory and it attempts a memory reclaim, which could
potentially call back into ext4. So we need to call
find_or_create_page() directly, and remove the __GFP_FP flag to avoid
this potential deadlock.
Thanks to Roland Dreier for reporting a lockdep warning which showed
this problem.

that gcc doesn't always manage to work out that fid is always set on the

* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

In the 'ubifs_recover_leb()' function, when we find corrupted
empty space, we dump 8K starting from the offset where the last
node ends. This is OK if the corrupted empty space is somewhere
near that offset. But if the corruption is far at the end of the
LEB, we will dump all 0xFF bytes and complitely ignore the
interesting data. This is observed on a PPC ("kilauea") with
NOR flash.
This patch changes the behavior and teaches UBIFS to print only
interesting data. I.e., now we find where corruption starts and
start dumping from that offset.

This patch fixes few minor things I've spotted while going through
code:
1. Better document return codes
2. If 'ubifs_scan_a_node()' returns some thing we do not expect,
treat this as an error.
3. Try to do recovery only when 'ubifs_scan()' returns %-EUCLEAN,
not on any error.
4. If empty space starts at a non-aligned address, print a message.

In case of corruptions, dump 8192 bytes instead of 4096. The
largest node is 4096+ bytes, so it is better to see a node
boundary, which is not always possible when only 4096 bytes
are printed.

UBIFS uses a bdi device per volume, but does not care to hand out unique
names to each of them. This causes an error when trying to mount more
than one volumes. Append the UBI volume and device ID to avoid that.

This patch adds the following minor optimization:
1. If write-buffer does not use the timer, indicate it with the
wbuf->no_timer variable, instead of using the wbuf->softlimit
variable. This is better because wbuf->softlimit is of ktime_t
type, and the ktime_to_ns function contains 64-bit multiplication.
2. Do not call the 'hrtimer_cancel()' function for write-buffers
which do not use timers.
3. Do not cancel the timer in 'ubifs_put_super()' because the
synchronization function does this.
This patch also removes a confusing comment.

Please remove them from all files:

I overlooked SG_DXFER_TO_FROM_DEV support when I converted sg to use
the block layer mapping API (2.6.28).
Douglas Gilbert explained SG_DXFER_TO_FROM_DEV:
http://www.spinics.net/lists/linux-scsi/msg37135.html
=
The semantics of SG_DXFER_TO_FROM_DEV were:
- copy user space buffer to kernel (LLD) buffer
- do SCSI command which is assumed to be of the DATA_IN
(data from device) variety. This would overwrite
some or all of the kernel buffer
- copy kernel (LLD) buffer back to the user space.
The idea was to detect short reads by filling the original
user space buffer with some marker bytes ("0xec" it would
seem in this report). The "resid" value is a better way
of detecting short reads but that was only added this century
and requires co-operation from the LLD.
=
This patch changes the block layer mapping API to support this
semantics. This simply adds another field to struct rq_map_data and
enables __bio_copy_iov() to copy data from user space even with READ
requests.
It's better to add the flags field and kills null_mapped and the new
from_user fields in struct rq_map_data but that approach makes it
difficult to send this patch to stable trees because st and osst
drivers use struct rq_map_data (they were converted to use the block
layer in 2.6.29 and 2.6.30). Well, I should clean up the block layer
mapping API.

Commit 1faa16d22877f4839bd433547d770c676d1d964c accidentally broke
the bdi congestion wait queue logic, causing us to wait on congestion
for WRITE (== 1) when we really wanted BLK_RW_ASYNC (== 0) instead.

This fixes a bug that checkpoint count gets wrong on errors when
deleting a series of checkpoints.
The count error is persistent since the checkpoint count is stored on
disk. Some userland programs refer to the count via ioctl, and this
bugfix is needed to prevent malfunction of such programs.

messages are mistakenly output by nilfs_dat_commit_start() function:
nilfs_dat_commit_start: vbn = 408463, start = 12506, end = 18446744073709551615, pbn = 530210

...
This suppresses these messages.

Leandro Lucarella gave me a report that nilfs gets stuck after its
write function fails.
The problem turned out to be caused by bugs which leave writeback flag
on pages. This fixes the problem by ensuring to clear the writeback
flag in error path.

The following error code handling in nilfs_segctor_write() function
wrongly converted negative error codes to a truth value (i.e. 1):
err = unlikely(err) ? : res;
which originaly meant to be
err = err ? : res;
This mis-conversion caused that write or sync functions receive the
unexpected error code. This fixes the bug by removing the unlikely
directive.

On windows servers, ATTR_READONLY apparently either has no meaning or
serves as some sort of queue to certain applications for unrelated
behavior. This MS kbase article has details:

Don't clear the write bits directory mode when ATTR_READONLY is set.

cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget
Rather than allocating an inode and filling it out, have
cifs_get_inode_info fill out a cifs_fattr and call cifs_iget. This means
a pretty hefty reorganization of cifs_get_inode_info.
For the readdir codepath, add a couple of new functions for filling out
cifs_fattr's from different FindFile response infolevels.
Finally, remove cifs_new_inode since there are no more callers.

When there's an open filehandle, SET_FILE_INFO is apparently preferred

infolevel via SET_FILE_INFO and switch cifs_setattr_unix to use the
new call when there's an open filehandle available.
