If anyone has any objections, please let me know. ------------------ From: chuguangqing [ Upstream commit 1534f72dc2a11ded38b0e0268fbcc0ca24e9fd4a ] The parent function ext4_xattr_inode_lookup_create already uses GFP_NOFS for memory alloction, so the function ext4_xattr_inode_cache_find should use same gfp_flag.
