From 313ed62a3ddc2cbe16087630910b41a87bfd9a1f Mon Sep 17 00:00:00 2001 From: Chengguang Xu Date: Fri, 31 Aug 2018 22:33:50 +0800 Subject: [PATCH] f2fs: cache NULL when both default_acl and acl are NULL default_acl and acl of newly created inode will be initiated as ACL_NOT_CACHED in vfs function inode_init_always() and later will be updated by calling xxx_init_acl() in specific filesystems. Howerver, when default_acl and acl are NULL then they keep the value of ACL_NOT_CACHED, this patch tries to cache NULL for acl/default_acl in this case.
