[PATCH] ocfs2: Fix a bug in direct IO read.
...with bs=4k cs=4k and nosparse.
2. create a small file(say less than 100 bytes) and we will create the file
which is allocated 1 cluster.
3. read 8196 bytes from the kernel using O_DIRECT which exceeds the limit.
4. The ocfs2 volume becomes read-only and dmesg shows:
OCFS2: ERROR (device sda13): ocfs2_direct_IO_get_blocks:
Inode 66010 has a hole at block 1
File system is now read-only due to the potential of on-disk corruption.
Please run fsck.ocfs2 once the file system is unmounted.
I have checked the code of 1.2 and copy the read check there.
And actually I think even with sparse-enabled, this read check is ok....

OCFS2 and direct-io writes
...appen when the extents
had previously been allocated with a RESVSP. It only to a couple of minor changes:
file.c:ocfs2_prepare_inode_for_write()
Don't disable direct_io if file is growing.
file.c:ocfs2_check_range_for_holes()
Don't treat unwritten extents as holes.
aops.c:ocfs2_direct_IO_get_blocks()
Map unwritten extents if they exists.
With these changes, a single/local OCFS2 filesystem will allow me to write/create files using
large, direct-io. All the write requests go straight through to the storage. And the write performance
is very close to that of XFS.
But, in a distributed e...

[PATCH 1/5] fs: allow short direct-io reads to be completed via buffered IO V2
V1->V2: Check to see if our current ppos is >= i_size after a short DIO read,
just in case it was actually a short read and we need to just return.
This is similar to what already happens in the write case. If we have a short
read while doing O_DIRECT, instead of just returning, fallthrough and try to
read the rest via buffered IO. BTRFS needs this because if we encounter a
compressed or
