See http://www.infradead.org/rpr.html Sender: linux-xfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-xfs@vger.kernel.org Move the extent zeroing case there for the XFS_BMAPI_ZERO flag outside the low-level allocator and into xfs_bmapi_allocate, where is still is in transaction context, but outside the very lowlevel code where it doesn't belong.
