hfsplus: rework processing errors in hfsplus_free_extents()

2012-12-21T01:40:19+00:00

hfsplus: add error checking for hfs_find_init()

2011-07-07T15:45:46+00:00

hfs_find_init() may fail with ENOMEM, but there are places, where
the returned value is not checked. The consequences can be very
unpleasant, e.g. kfree uninitialized pointer and
inappropriate mutex unlocking.

The patch adds checks for errors in hfs_find_init().

hfsplus: fix overflow in hfsplus_get_block

2011-06-30T11:40:58+00:00

For filesystems larger than 2TB the final sector number passed to
map_bh might overflow the range representable in a 32-bit data type.
Make sure we use a sector_t for it and the arithmetics calculating it.

hfsplus: fix up a comparism in hfsplus_file_extend

2011-02-03T23:34:18+00:00

Revert an incorrect hunk from commit b2837fcf4994e699a4def002e26f274d95b387c1,

	"hfsplus: %L-to-%ll, macro correction, and remove unneeded braces"

revert a pointless change of comparism operation argument order, which turned
out to not even be equivalent.
