Subject: [PATCH v2 05/11] NFSD: Clean up switch statement in nfsd_dispatch()
Date: Tue, 29 Sep 2020 10:04:03 -0400 [thread overview]
Message-ID: <160138824365.2558.3730697804206958272.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <160138785101.2558.11821923574884893011.stgit@klimt.1015granger.net>
Reorder the arms so the compiler places checks for the most frequent
cases first.
