From: Al Viro Date: Fri, 12 Sep 2025 15:52:41 +0000 (-0400) Subject: simplify nfs_atomic_open_v23() X-Git-Tag: v6.18-rc1~125^2~3 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aae9db5739164353fa1894db000fabad940a835b;p=thirdparty%2Fkernel%2Flinux.git simplify nfs_atomic_open_v23() 1) finish_no_open() takes ERR_PTR() as dentry now. 2) caller of ->atomic_open() will call d_lookup_done() itself, no need to do it here.
