f2fs: enhance multi-threads performance
Previously, f2fs_write_data_pages has a mutex, sbi->writepages, to serialize data writes to maximize write bandwidth, while sacrificing multi-threads performance. Practically, however, multi-threads environment is much more important for users. So this patch tries to remove the mutex. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
