| * mbcache: Remove unused featuresAndreas Gruenbacher2010-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | The mbcache code was written to support a variable number of indexes, but all the existing users use exactly one index. Simplify to code to support only that case. There are also no users of the cache entry free operation, and none of the users keep extra data in cache entries. Remove those features as well.

| * remove inode_setattrChristoph Hellwig2010-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

| * introduce __block_write_beginChristoph Hellwig2010-08-09
| | | | | | | | | | | | | | | | | | | | | | | | Split up the block_write_begin implementation - __block_write_begin is a new trivial wrapper for block_prepare_write that always takes an already allocated page and can be either called from block_write_begin or filesystem code that already has a page allocated. Remove the handling of already allocated pages from block_write_begin after switching all callers that do it to __block_write_begin.

| | | | | | | | | | | | | | | | | | | | | | | | Move the call to vmtruncate to get rid of accessive blocks to the callers in prepearation of the new truncate calling sequence. This was only done for DIO_LOCKING filesystems, so the __blockdev_direct_IO_newtrunc variant was not needed anyway. Get rid of blockdev_direct_IO_no_locking and its _newtrunc variant while at it as just opencoding the two additional paramters is shorted than the name suffix.

| * | ext4: Adding error check after calling ext4_mb_regular_allocator()Aditya Kali2010-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the bitmap block on disk is bad, ext4_mb_load_buddy() returns an error. This error is returned to the caller, ext4_mb_regular_allocator() and then to ext4_mb_new_blocks(). But ext4_mb_new_blocks() did not check for the return value of ext4_mb_regular_allocator() and would repeatedly try to load the bitmap block. The fix simply catches the return value and exits out of the 'repeat' loop after cleanup. We also take the opportunity to clean up the error handling in ext4_mb_new_blocks().

| * | ext4: Fix dirtying of journalled buffers in data=journal modeJan Kara2010-08-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In data=journal mode, we still use block_write_begin() to prepare page for writing. This function can occasionally mark buffer dirty which violates journalling assumptions - when a buffer is part of a transaction, it should be dirty and a buffer can be already part of a forget list of some transaction when block_write_begin() gets called. This violation of journalling assumptions then results in "JBD: Spotted dirty metadata buffer..." warnings. In fact, temporary dirtying the buffer while the page is still locked does not really cause problems to the journalling because we won't write the buffer until the page gets unlocked. So we just have to make sure to clear dirty bits before unlocking the page. Signed-off-by: Jan Kara <jack@suse.cz>
| * | ext4: re-inline ext4_rec_len_(to|from)_disk functionsEric Sandeen2010-08-05

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6b0310fbf087ad6 caused a regression resulting in deadlocks when freezing a filesystem which had active IO; the vfs_check_frozen level (SB_FREEZE_WRITE) did not let the freeze-related IO syncing through. Duh. Changing the test to FREEZE_TRANS should let the normal freeze syncing get through the fs, but still block any transactions from starting once the fs is completely frozen. I tested this by running fsstress in the background while periodically snapshotting the fs and running fsck on the result. I ran into occasional deadlocks, but different ones. I think this is a fine fix for the problem at hand, and the other deadlocky things will need more investigation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When journaled quota options are not specified, we do writes to quota files just in data=ordered mode.

Since quota actually is filesystem metadata, the easiest way to get rid of the warning is to always treat quota writes as metadata...

If you have a multiple (say, a 128k IO on a 64k stripe) you may end up unaligned.

It adds iocb and result fields to struct ext4_io_end_t, so that we can call aio_complete from ext4_end_io_nolock() after the extent conversion has finished.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have experienced bitmap inconsistencies after crash during file delete under heavy load. The crash is not file system related and I the following patch in ext4_free_branches() fixes the recovery problem. If the transaction is restarted and there is a crash before the new transaction is committed, then after recovery, the blocks that this indirect block points to have been freed, but the indirect block itself has not been freed and may still point to some of the free blocks (because of the ext4_forget()). So ext4_forget() should be called inside ext4_free_blocks() to avoid this problem. Signed-off-by: Amir Goldstein <amir73il@users.sf.net> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need to set s_dirt in most of the ext4 code when journaling is enabled. In ext3/4 some of the summary statistics for # of free inodes, blocks, and directories are calculated from the per-block group statistics when the file system is mounted or unmounted. As a result the superblock doesn't have to be updated, either via the journal or by setting s_dirt. There are a few exceptions, most notably when resizing the file system, where the superblock needs to be modified --- and in that case it should be done as a journalled operation if possible, and s_dirt set only in no-journal mode. This patch will optimize out some unneeded disk writes when using ext4 with a journal. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

| * ext4: Make sure the MOVE_EXT ioctl can't overwrite append-only filesTheodore Ts'o2010-06-02
| | | | | | | | | | | | | | | | | | | | Dan Roseberg has reported a problem with the MOVE_EXT ioctl. If the donor file is an append-only file, we should not allow the operation to proceed, lest we end up overwriting the contents of an append-only file.
