* fs: btrfs: Fix usage of uninitialized variablesMarek Behún2017-10-163-3/+3
| | | | | | | | | | | The variable res should be initialized to 0 in these functions, because if the searched key is not found, the variable is used uninitialized.

* fs: btrfs: Add single-device read-only BTRFS implementationMarek Behún2017-10-0212-0/+1841
| | | | | | | | | | | | | | | | | | | | | | | | | 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).

* fs: btrfs: Add disk-to-cpu and cpu-to-disk conversion functionsMarek Behún2017-10-021-0/+176
| | | | | | | | | | | | | | | BTRFS on disk structures are stored in Little Endian. Add functions to convert this structures to cpu and to disk format. On Little Endian hosts, these functions do nothing. On Big Endian the CALL_MACRO_FROM_EACH from variadic-macro.h is used to define all the members for each structure on which cpu_to_le* or le*_to_cpu is to be called.
