David Sterba 27942c9971 btrfs: fix messages after changing compression level by remount ... Reported by Forza on IRC that remounting with compression options does not reflect the change in level, or at least it does not appear to do so according to the messages: mount -o compress=zstd:1 /dev/sda /mnt mount -o remount,compress=zstd:15 /mnt does not print the change to the level to syslog: [ 41.366060] BTRFS info (device vda): use zstd compression, level 1 [ 41.368254] BTRFS info (device vda): disk space caching is enabled [ 41.390429] BTRFS info (device vda): disk space caching is enabled What really happens is that the message is lost but the level is actualy changed. There's another weird output, if compression is reset to 'no': [ 45.413776] BTRFS info (device vda): use no compression, level 4 To fix that, save the previous compression level and print the message in that case too and use separate message for 'no' compression.
