f2fs: fix to keep project quota consistent
This patch does below changes to keep consistence of project quota data in sudden power-cut case: - update inode.i_projid and project quota atomically under lock_op() in f2fs_ioc_setproject() - recover inode.i_projid and project quota in recover_inode() Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
