When we close a file, we remove preallocated blocks from it. But this
truncation was not protected by i_mutex and thus it could have raced with a
write through a different fd and cause crashes or even filesystem corruption.

So far we preallocated blocks also for directories but that brings a
problem, when to get rid of preallocated blocks we don't need. So far
we removed them in udf_clear_inode() which has a disadvantage that
1) blocks are unavailable long after writing to a directory finished
and thus one can get out of space unnecessarily early
2) releasing blocks from udf_clear_inode is problematic because VFS
does not expect us to redirty inode there and it also slows down
memory reclaim.
So preallocate blocks only for regular files where we can drop preallocation
in udf_release_file.

Currenly vfs_fsync(_range) first calls filemap_fdatawrite to write out
the data, the calls into ->fsync to write out the metadata and then finally
calls filemap_fdatawait to wait for the data I/O to complete. What sounds
like a clever micro-optimization actually is nast trap for many filesystems.
For many modern filesystems i_size or other inode information is only
updated on I/O completion and we need to wait for I/O to finish before
we can write out the metadata. For old fashionen filesystems that
instanciate blocks during the actual write and also update the metadata
at that point it opens up a large window were we could expose uninitialized
blocks after a crash. While a few filesystems that need it already wait
for the I/O to finish inside their ->fsync methods it is rather suboptimal
as it is done under the i_mutex and also always for the whole file instead
of just a part as we could do for O_SYNC handling.
Here is a small audit of all fsync instances in the tree:
- spufs_mfc_fsync:
- ps3flash_fsync:
- vol_cdev_fsync:
- printer_fsync:
- fb_deferred_io_fsync:
- bad_file_fsync:
- simple_sync_file:
don't care - filesystems/drivers do't use the page cache or are
purely in-memory.
- simple_fsync:
- file_fsync:
- affs_file_fsync:
- fat_file_fsync:
- jfs_fsync:
- ubifs_fsync:
- reiserfs_dir_fsync:
- reiserfs_sync_file:
never touch pagecache themselves. We need to wait before if we do
not want to expose stale data after an allocation.
- afs_fsync:
- fuse_fsync_common:
do the waiting writeback itself in awkward ways, would benefit from
proper semantics
- block_fsync:
Does a filemap_write_and_wait on the block device inode. Because we
now have f_mapping that is the same inode we call it on in vfs_fsync.
So just removing it and letting the VFS do the work in one go would
be an improvement.
- btrfs_sync_file:
- cifs_fsync:
- xfs_file_fsync:
need the wait first and currently do it themselves. would benefit from
doing it outside i_mutex.
- coda_fsync:
- ecryptfs_fsync:
- exofs_file_fsync:
- shm_fsync:
only passes the fsync through to the lower layer
- ext3_sync_file:
doesn't seem to care, comments are confusing.
- ext4_sync_file:
would need the wait to work correctly for delalloc mode with late
i_size updates. Otherwise the ext3 comment applies.
currently implemens it's own writeback and wait in an odd way,
could benefit from doing it properly.
- gfs2_fsync:
not needed for journaled data mode, but probably harmless there.
Currently writes back data asynchronously itself. Needs some
major audit.
- hostfs_fsync:
just calls fsync/datasync on the host FD. Without the wait before
data might not even be inflight yet if we're unlucky.
- hpfs_file_fsync:
- ncp_fsync:
no-ops. Dangerous before and after.
- jffs2_fsync:
just calls jffs2_flush_wbuf_gc, not sure how this relates to data.
- nfs_fsync_dir:
just increments stats, claims all directory operations are synchronous
- nfs_file_fsync:
only writes out data??? Looks very odd.
- nilfs_sync_file:
looks like it expects all data done, but not sure from the code
- ntfs_dir_fsync:
- ntfs_file_fsync:
appear to do their own data writeback. Very convoluted code.
- ocfs2_sync_file:
does it's own data writeback, but no wait. probably needs the wait.
- smb_fsync:
according to a comment expects all pages written already, probably needs
the wait before.
This patch only changes vfs_fsync_range, removal of the wait in the methods
that have it is left to the filesystem maintainers. Note that most
filesystems really do need an audit for their fsync methods given the
gems found in this very brief audit.

Actually, nilfs is NOT a filesystem came from other operating systems,

The nilfs_bmap_lookup() is now a wrapper function of
nilfs_bmap_lookup_at_level().
This moves the nilfs_bmap_lookup() to a header file converting it to
an inline function and gives an opportunity for optimization.
Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
The current btree code is written so that btree functions call dat
operations via wrapper functions in bmap.c when they allocate, free,
or modify virtual block addresses.
This abstraction requires additional function calls and causes
frequent call of nilfs_bmap_get_dat() function since it is used in the
every wrapper function.
This removes the wrapper functions and makes them available from
btree.c and direct.c, which will increase the opportunity of
compiler optimization.

Even though many btree functions take a btree object as their first

This is a re-revised patch to shorten freeze period.
This version include a fix of the bug Konishi-san mentioned last time.
When GC is runnning, GC moves live block to difference segments.
Copying live blocks into memory is done in a transaction,
however it is not necessarily to be in the transaction.
This patch will get the nilfs_ioctl_move_blocks() out from
transaction lock and put it before the transaction.
I ran sysbench fileio test against nilfs partition.
I copied some DVD/CD images and created snapshot to create live blocks
before starting the benchmark.
Followings are summary of rc8 and rc8 w/ the patch of per-request
statistics, which is min/max and avg. I ran each test three times and
bellow is average of those numers.
According to this benchmark result, average time is slightly degrated.
However, worstcase (max) result is significantly improved.
This can address a few seconds write freeze.

This removes nilfs_write_super and commit super block in nilfs
internal thread, instead of periodic write_super callback.
VFS layer calls ->write_super callback periodically. However,
it looks like that calling back is ommited when disk I/O is busy.
And when cleanerd (nilfs GC) is runnig, disk I/O tend to be busy thus
nilfs superblock is not synchronized as nilfs designed.
To avoid it, syncing superblock by nilfs thread instead of pdflush.

The current metadata file code skips disk address lookup for its data
block if the buffer has a mapped flag.
This has a potential risk to cause read request to be performed
against the stale block address that GC moved, and it may lead to meta
data corruption. The mapped flag is safe if the buffer has an
uptodate flag, otherwise it may prevent necessary update of disk
address in the next read.
This will avoid the potential problem by ensuring disk address lookup
before reading metadata block even for buffers with the mapped flag.
