Subject: Re: [PATCH 2/4 v2] avoid perform unwritten convertion for direct
	IO over non fallocated space

I fixed up some white space issues, and rewrote the patch description
as follows:

ext4: skip conversion of uninit extents after direct IO if there isn't any

At the end of direct I/O operation, ext4_ext_direct_IO() always called
ext4_convert_unwritten_extents(), regardless of whether there were any
unwritten extents involved in the I/O or not.

This commit adds a state flag so that ext4_ext_direct_IO() only calls
ext4_convert_unwritten_extents() when necessary.

Added to the patch queue.
