Subject: [PATCH] btrfs-progs: receive: add tests for basic encoded_write
dbfe2d
 send/receive
dbfe2d
dbfe2d
Adapt the existing send/receive tests by passing '-o compress-force' to
dbfe2d
the mount commands in a new test. After writing a few files in the
dbfe2d
various compression formats, send/receive them with and without
dbfe2d
--force-decompress to test both the encoded_write path and the fallback
dbfe2d
to decode+write.
