Subject: [PATCH RFC v1 0/5]Factor common code from convert and split unwritten.
Date: Sat, 23 Apr 2011 01:44:14 -0700 [thread overview]
Message-ID: <1303548259-28311-1-git-send-email-xiaoqiangnk@gmail.com> (raw)
v0->v1:
fix a bug in ext4_ext_convert_to_initialized() reported by
Allison <achender@linux.vnet.ibm.com>.
optimize ext4_ext_convert_to_initialized().
-- factor common code
These patches factor common code from ext4_ext_convert_to_initialized() and
ext4_split_unwritten_extents() so that extent-move-on-write in snapshot and
punch hole can be built on the common code.
-- optimization
the 4th and the 5th patch optimize ext4_ext_convert_to_initialized() by
zeroing out in memory.
[PATCH RFC v1 1/5] ext4:Add a function merging extent right and left.
[PATCH RFC v1 2/5] ext4:Add two functions splitting an extent.
[PATCH RFC v1 3/5] ext4:Reimplement convert and split_unwritten.
[PATCH RFC v1 4/5] ext4: Add a function ext4_ext_zeroout_mem().
[PATCH RFC v1 5/5] ext4: optimize ext4_ext_convert_to_initialized().
