Subject: [PATCH v4 20/20] ext4: Allow punch hole with bigalloc enabled
Date: Tue, 14 May 2013 18:37:34 +0200	[thread overview]
Message-ID: <1368549454-8930-21-git-send-email-lczerner@redhat.com> (raw)
In-Reply-To: <1368549454-8930-1-git-send-email-lczerner@redhat.com>

In commits 5f95d21fb6f2aaa52830e5b7fb405f6c71d3ab85 and
30bc2ec9598a1b156ad75217f2e7d4560efdeeab we've reworked punch_hole
implementation and there is noting holding us back from using punch hole
on file system with bigalloc feature enabled.

This has been tested with fsx and xfstests.
