Between the 2 calls the size shouldn't change. So remove the unnecessary -ERANGE error check. Signed-off-by: Chengguang Xu Reviewed-by: Nikolay Borisov --- v4: - Split patch to series. v3: - Fix some toher bad practices. - Add more information to commit log. v2: - Avoid errno overriding instead of print error message in error case. - Chagne commit log for better understanding. fs/btrfs/acl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/btrfs/acl.c b/fs/btrfs/acl.c index 83fdd80c51c6..a1d7211c8884 100644 --- a/fs/btrfs/acl.c +++ b/fs/btrfs/acl.c @@ -42,7 +42,7 @@ struct posix_acl *btrfs_get_acl(struct inode *inode, int type) } if (size > 0) { acl = posix_acl_from_xattr(&init_user_ns, value, size); - } else if (size == -ERANGE || size == -ENODATA || size == 0) { + } else if (size == -ENODATA || size == 0) { acl = NULL; } else { acl = ERR_PTR(-EIO); -- 2.17.1
