ext4: use proper little-endian bitops

2011-12-29T01:32:07+00:00

ext4_{set,clear}_bit() is defined as __test_and_{set,clear}_bit_le() for
ext4.  Only two ext4_{set,clear}_bit() calls check the return value.  The
rest of calls ignore the return value and they can be replaced with
__{set,clear}_bit_le().

This changes ext4_{set,clear}_bit() from __test_and_{set,clear}_bit_le()
to __{set,clear}_bit_le() and introduces ext4_test_and_{set,clear}_bit()
for the two places where old bit needs to be returned.

This ext4_{set,clear}_bit() change is considered safe, because if someone
uses these macros without noticing the change, new ext4_{set,clear}_bit
don't have return value and causes compiler errors where the return value
is used.

This also removes unused ext4_find_first_zero_bit().

ext4: fix error handling on inode bitmap corruption

2011-12-18T22:37:02+00:00

When insert_inode_locked() fails in ext4_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 the 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().

ext4: fix quota accounting during migration

2011-10-29T13:05:00+00:00

The tmp_inode should have same uid/gid as the original inode.
Otherwise new metadata blocks will be accounted to wrong quota-id,
which will result in a quota leak after the inode migration is
completed.

ext4: functions should not be declared extern

2011-10-18T14:57:51+00:00

The function declarations in ext4.h are already marked extern, so it's
not necessary to do so in the .c files.

This quiets the sparse noise:

warning: function 'ext4_flush_completed_IO' with external linkage has definition
warning: function 'ext4_init_inode_table' with external linkage has definition
