Subject: Re: [PATCH 2/2] ext4: reserve hole in the migration to non-extent
 based file

Applied, although I reworded the commit description a little:

ext4: correctly migrate a file with a hole at the beginning

Currently ext4_ind_migrate() doesn't correctly handle a file which
contains a hole at the beginning of the file.  This caused the migration
to be done incorrectly, and then if there is a subsequent following
delayed allocation write to the "hole", this would reclaim the same data
blocks again and results in fs corruption.

...

Thanks!!
