Subject: [PATCH] nfs: nfs3acl: drop useless assignment in nfs3_get_acl()
Date: Wed, 9 Apr 2025 23:36:33 +0300	[thread overview]
Message-ID: <c32dced7-a4fa-43c0-aafe-ef6c819c2f91@omp.ru> (raw)

In nfs3_get_acl(), the local variable status is assigned the result of
nfs_refresh_inode() inside the *switch* statement, but that value gets
overwritten in the next *if* statement's true branch and is completely
ignored if that branch isn't taken...

Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
