Subject: [PATCH 0/3] ext4: Improve parallel I/O performance on NVDIMM
Date: Fri, 1 Apr 2016 23:09:35 -0400 [thread overview]
Message-ID: <1459566578-30221-1-git-send-email-Waiman.Long@hpe.com> (raw)
This patchset aims to improve parallel I/O performance of the ext4
filesystem on fast storage devices like NVDIMM.
Patch 1 eliminates duplicated inode_dio_begin()/inode_dio_end() calls.
Patch 2 provides a set of simple percpu statistics count helper functions.
Patch 3 converts some ext4 statistics counts into percpu counts using
the helper functions.
Waiman Long (3):
ext4: Pass in DIO_SKIP_DIO_COUNT flag if inode_dio_begin() called
percpu_stats: Simple per-cpu statistics count helper functions
ext4: Make cache hits/misses per-cpu counts
