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
