Pull btrfs fixes from David Sterba:
- fixup warning when allocating memory for readahead, __GFP_NOWARN was
accidentally dropped when setting mapping constraints
- in tracepoint of file sync, fix sleeping in atomic context when
handling dentries
- harden initial loading of block group on crafted/fuzzed images,
iterate all chunk mapping entries unconditionally
- fix freeing pages of submitted io after checking for errors
- fix incorrect inode size after remount when using fallocate KEEP_SIZE
mode (also requires disabled 'no-holes' feature)
