Test that fsync operations preserve extents allocated with fallocate(2) that are placed beyond a file's size. This test is motivated by a bug found in btrfs where unwritten extents beyond the inode's i_size were not preserved after a fsync and power failure. The btrfs bug is fixed by the following patch for the linux kernel: "Btrfs: fix loss of prealloc extents past i_size after fsync log replay" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
