f2fs: compress: fix to cover f2fs_disable_compressed_file() w/ i_sem
- f2fs_disable_compressed_file
- check inode_has_data
- f2fs_file_mmap
- mkwrite
- f2fs_get_block_locked
: update metadata in compressed
inode's disk layout
- fi->i_flags &= ~F2FS_COMPR_FL
- clear_inode_flag(inode, FI_COMPRESSED_FILE);
we should use i_sem lock to prevent above race case.
