Marcos Paulo de Souza 282dd7d771 btrfs: reset compression level for lzo on remount ... Currently a user can set mount "-o compress" which will set the compression algorithm to zlib, and use the default compress level for zlib (3): relatime,compress=zlib:3,space_cache If the user remounts the fs using "-o compress=lzo", then the old compress_level is used: relatime,compress=lzo:3,space_cache But lzo does not expose any tunable compression level. The same happens if we set any compress argument with different level, also with zstd. Fix this by resetting the compress_level when compress=lzo is specified. With the fix applied, lzo is shown without compress level: relatime,compress=lzo,space_cache CC: stable@vger.kernel.org # 4.4+ Signed-off-by: Marcos Paulo de Souza <mpdesouza@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>		2020-08-19 18:39:12 +02:00
