Marek Behún	ecab881c7f	fs: btrfs: Fix usage of uninitialized variables ... The variable res should be initialized to 0 in these functions, because if the searched key is not found, the variable is used uninitialized.

Marek Behún	21a14facb1	fs: btrfs: Add single-device read-only BTRFS implementation ... This adds the proper implementation for the BTRFS filesystem. The implementation currently supports only read-only mode and the filesystem can be only on a single device. Checksums of data chunks is unimplemented. Compression is implemented (ZLIB + LZO).
