From 1534f72dc2a11ded38b0e0268fbcc0ca24e9fd4a Mon Sep 17 00:00:00 2001 From: chuguangqing Date: Wed, 6 Aug 2025 10:28:49 +0800 Subject: [PATCH] fs: ext4: change GFP_KERNEL to GFP_NOFS to avoid deadlock 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.
