Subject: [PATCH 5/8] fs/9p: One function call less in v9fs_vfs_atomic_open_dotl()
 after error detection

From: Markus Elfring <>
Date: Sun, 28 Dec 2014 09:29:40 +0100

The p9_client_clunk() function was called in three cases by the
v9fs_vfs_atomic_open_dotl() function during error handling even if the passed
variable "fid" contained a null pointer.

This implementation detail could be improved by the adjustment of jump targets.
Let us delete also an unnecessary variable assignment there.
