Subject: [PATCH] btrfs-progs: fix defrag -c option parsing
|
|
|
|
The refactoring f3a132fa1b8c ("btrfs-progs: factor out compression type
|
|
name parsing to common utils") caused a bug with parsing option -c with
|
|
defrag:
|
|
|
|
# btrfs fi defrag -v -czstd file
|
|
ERROR: unknown compression type: zstd
|
|
|
|
# btrfs fi defrag -v -clzo file
|
|
ERROR: unknown compression type: lzo
|
|
|
|
# btrfs fi defrag -v -czlib file
|
|
ERROR: unknown compression type: zlib
|
|
|
|
Fix it by properly checking the value representing unknown compression
|
|
algorithm.

|
