ext3: Fix fdatasync() for files with only i_size changes

2012-09-19T14:04:37+00:00

commit 156bddd8e505b295540f3ca0e27dda68cb0d49aa upstream.

Code tracking when transaction needs to be committed on fdatasync(2) forgets
to handle a situation when only inode's i_size is changed. Thus in such
situations fdatasync(2) doesn't force transaction with new i_size to disk
and that can result in wrong i_size after a crash.

Fix the issue by updating inode's i_datasync_tid whenever its size is
updated.

ext3: Fix error handling on inode bitmap corruption

2012-05-30T23:43:52+00:00

commit 1415dd8705394399d59a3df1ab48d149e1e41e77 upstream.

When insert_inode_locked() fails in ext3_new_inode() it most likely
means inode bitmap got corrupted and we allocated again inode which
is already in use. Also doing unlock_new_inode() during error recovery
is wrong since inode does not have I_NEW set. Fix the problem by jumping
to fail: (instead of fail_drop:) which declares filesystem error and
does not call unlock_new_inode().

ext3: Don't warn from writepage when readonly inode is spotted after error

2012-01-12T19:29:32+00:00

commit 33c104d415e92a51aaf638dc3d93920cfa601e5c upstream.

WARN_ON_ONCE(IS_RDONLY(inode)) tends to trip when filesystem hits error and is
remounted read-only. This unnecessarily scares users (well, they should be
scared because of filesystem error, but the stack trace distracts them from the
right source of their fear ;-). We could as well just remove the WARN_ON but
it's not hard to fix it to not trip on filesystem with errors and not use more
cycles in the common case so that's what we do.

2011-10-10T16:25:59+00:00

There are no user of EXT3_IOC32_WAIT_FOR_READONLY and also it is
broken. No one set the set_ro_timer, no one wake up us and our
state is set to TASK_INTERRUPTIBLE not RUNNING. So remove it.
