v9fs_put_str used to store pointer to the source string, instead of the
cbuf copy. This patch corrects it.

There is a code path that passed size to ext2_xattr_set
(ext3_xattr_set_handle) before initializing it. The callees don't use the
value in that case, but gcc cannot tell. Always initialize size to get rid

This fixes the code like this:
bh = sb_find_get_block (sb, tmp + j);
if ((bh && DATA_BUFFER_USED(bh)) || tmp != fs32_to_cpu(sb, *p)) {
retry = 1;
brelse (bh);
goto next1;
}
bforget (bh);
sb_find_get_block() ordinarily returns a buffer_head with b_count>=2, and
this code assume that in case if "b_count>1" buffer is used, so this caused
infinite loop.
(akpm: that is-the-buffer-busy code is incomprehensible. Good riddance. Use
of block_truncate_page() seems sane).

"rm" command, on file system with "ufs1" type cause system hang up. This
is, in fact, not so bad as it seems to be, because of after that in "kernel
control path" there are 3-4 places which may cause "oops".
So the first patch fix oopses, and the second patch fix "kernel hang up".
"oops" appears because of reading of group's summary info partly wrong, and
access to not first group's summary info cause "oops".

Most of the 64 bit architectures will zero extend the first argument to
compat_sys_{openat,newfstatat,futimesat} which will fail if the 32 bit
syscall was passed AT_FDCWD (which is a small negative number). Declare
the first argument to be an unsigned int which will force the correct
sign extension when the internal functions are called in each case.
Also, do some small white space cleanups in fs/compat.c.

If the server returns NLM_LCK_DENIED_NOLOCKS, we currently retry the
entire NLM_CANCEL request. This may end up looping forever unless the
server changes its mind (why would it do that, though?).

In data=journal mode, reiserfs writepage needs to make sure not to trigger
transactions while being run under PF_MEMALLOC. This patch makes sure to
redirty the page instead of forcing a transaction start in this case.
Also, calling filemap_fdata* in order to trigger io on the block device can
cause lock inversions on the page lock. Instead, do simple batching from
flush_commit_list.

After a transaction has closed but before it has finished commit, there is
a window where data=ordered mode requires invalidatepage to pin pages
instead of freeing them. This patch fixes a race between the
invalidatepage checks and data=ordered writeback, and it also adds a check
to the reiserfs write_ordered_buffers routines to write any anonymous
buffers that were dirtied after its first writeback loop.
That bug works like this:
proc1: transaction closes and a new one starts
proc1: write_ordered_buffers starts processing data=ordered list
proc1: buffer A is cleaned and written
proc2: buffer A is dirtied by another process
proc2: File is truncated to zero, page A goes through invalidatepage
proc2: reiserfs_invalidatepage sees dirty buffer A with reiserfs
journal head, pins it
proc1: write_ordered_buffers frees the journal head on buffer A
At this point, buffer A stays dirty forever

Migrate a page with buffers without requiring writeback
This introduces a new address space operation migratepage() that may be used
by a filesystem to implement its own version of page migration.
A version is provided that migrates buffers attached to pages. Some
filesystems (ext2, ext3, xfs) are modified to utilize this feature.
The swapper address space operation are modified so that a regular
migrate_page() will occur for anonymous pages without writeback (migrate_pages
forces every anonymous page to have a swap entry).

2.6.15's hugepage faulting introduced huge_pages_needed accounting into
hugetlbfs: to count how many pages are already in cache, for spot check on
how far a new mapping may be allowed to extend the file. But it's muddled:
each hugepage found covers HPAGE_SIZE, not PAGE_SIZE. Once pages were
already in cache, it would overshoot, wrap its hugepages count backwards,
and so fail a harmless repeat mapping with -ENOMEM. Fixes the problem
found by Don Dupuis.

OpenBSD doesn't see "." correctly in directories created by Linux. Copying
files over several KB will buy you infinite loop in __getblk_slow().
Copying files smaller than 1 KB seems to be OK. Sometimes files will be

next file with truncated size.

While asynchronous reads mean a performance improvement in most cases, if
the filesystem assumed that reads are synchronous, then async reads may
degrade performance (filesystem may receive reads out of order, which can
confuse it's own readahead logic).
With sshfs a 1.5 to 4 times slowdown can be measured.
There's also a need for userspace filesystems to know whether asynchronous
reads are supported by the kernel or not.
To achive these, negotiate in the INIT request whether async reads will be
used and the maximum readahead value. Update interface version to 7.6
If userspace uses a version earlier than 7.6, then disable async reads, and
set maximum readahead value to the maximum read size, as done in previous
versions.

The compat layer timeout handling changes in:
9f72949f679df06021c9e43886c9191494fdb007
are busted. This is most easily seen with an X application
that uses sub-second select/poll timeout such as emacs. You
hit a key and it takes a second or so before the app responds.
The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it
should instead be using {tv_usec,ts_nsec}, which perfectly explains
the observed incorrect behavior.
