Hi David, Today's linux-next merge of the btrfs-kdave tree got a conflict in: fs/btrfs/props.c between commit: f764b4f4bb26 ("btrfs: property: Set incompat flag if lzo/zstd compression is set") from the btrfs-fixes tree and commit: e37739baf401 ("btrfs: allow setting zstd level") from the btrfs-kdave tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc fs/btrfs/props.c index dc6140013ae8,c85bb04a1cc3..000000000000 --- a/fs/btrfs/props.c +++ b/fs/btrfs/props.c @@@ -391,17 -390,14 +391,17 @@@ static int prop_compression_apply(struc return 0; } - if (!strncmp("lzo", value, 3)) + if (!strncmp("lzo", value, 3)) { type = BTRFS_COMPRESS_LZO; - else if (!strncmp("zlib", value, 4)) + btrfs_set_fs_incompat(fs_info, COMPRESS_LZO); + } else if (!strncmp("zlib", value, 4)) { type = BTRFS_COMPRESS_ZLIB; - } else if (!strncmp("zstd", value, len)) { - else if (!strncmp("zstd", value, 4)) ++ } else if (!strncmp("zstd", value, 4)) { type = BTRFS_COMPRESS_ZSTD; - else + btrfs_set_fs_incompat(fs_info, COMPRESS_ZSTD); + } else { return -EINVAL; + } BTRFS_I(inode)->flags &= ~BTRFS_INODE_NOCOMPRESS; BTRFS_I(inode)->flags |= BTRFS_INODE_COMPRESS;
