ext4: remove trailing newlines from ext4_msg() and ext4_error() messages

2012-03-20T03:13:43+00:00

The functions ext4_msg() and ext4_error() already tack on a trailing
newline, so remove the unnecessary extra newline.

ext4: fix race when setting bitmap_uptodate flag

2012-02-20T22:52:46+00:00

In ext4_read_{inode,block}_bitmap() we were setting bitmap_uptodate()
before submitting the buffer for read.  The is bad, since we check
bitmap_uptodate() without locking the buffer, and so if another
process is racing with us, it's possible that they will think the
bitmap is uptodate even though the read has not completed yet,
resulting in inodes and blocks potentially getting allocated more than
once if we get really unlucky.

ext4: fold ext4_claim_inode into ext4_new_inode

2012-02-07T01:12:03+00:00

The function ext4_claim_inode() is only called by one function,
ext4_new_inode(), and by folding the functionality into
ext4_new_inode(), we can remove almost 50 lines of code, and put all
of the logic of allocating a new inode into a single place.

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().
