Date: Tue, 14 Aug 2018 22:16:32 +0800 From: Chengguang Xu <cgxu519@....com> To: jack@...e.com, tytso@....edu, adilger.kernel@...ger.ca, jaegeuk@...nel.org, yuchao0@...wei.com, shaggy@...nel.org, hubcap@...ibond.com, martin@...ibond.com Cc: devel@...ts.orangefs.org, linux-kernel@...r.kernel.org, linux-ext4@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net, jfs-discussion@...ts.sourceforge.net, Chengguang Xu <cgxu519@....com> Subject: [PATCH 3/5] 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.
