12 ext4: fast commit recovery path
13
14 This patch adds fast commit recovery path support for Ext4 file
15 system. We add several helper functions that are similar in spirit to
16 e2fsprogs journal recovery path handlers. Example of such functions
17 include - a simple block allocator, idempotent block bitmap update
18 function etc. Using these routines and the fast commit log in the fast
19 commit area, the recovery path (ext4_fc_replay()) performs fast commit
20 log recovery.
