X-Git-Tag: v6.3.0~13
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=c92d3040144be827dc4670a849b5e2e0f7858cda;p=xfsprogs-dev.git

xfs: use xfs_bmap_longest_free_extent() in filestreams

Source kernel commit: 05cf492a8d01f48d4b8d8f0b93f2d75de7349f12

The code in xfs_bmap_longest_free_extent() is open coded in
xfs_filestream_pick_ag(). Export xfs_bmap_longest_free_extent and
call it from the filestreams code instead.
