Subject: [PATCH 12/13] fuse: drop redundant arguments to fuse_perform_write
Date:   Fri, 19 May 2023 11:35:20 +0200
Message-Id: <20230519093521.133226-13-hch@lst.de>
In-Reply-To: <20230519093521.133226-1-hch@lst.de>

Precedence: bulk

pos is always equal to iocb->ki_pos, and mapping is always equal to
iocb->ki_filp->f_mapping.
