Subject: [PATCH 8/8] orangefs: use ->f_mapping
Date: Sat, 20 Aug 2022 21:20:50 +0100	[thread overview]
Message-ID: <YwFCIkDT7sFO1D9N@ZenIV> (raw)
In-Reply-To: <YwFANLruaQpqmPKv@ZenIV>

... and don't check for impossible conditions - file_inode() is
never NULL in anything seen by ->release() and neither is its
->i_mapping.
