Subject: fuse: drop redundant arguments to fuse_perform_write
X-Git-Tag: v6.6.7~2549^2~207
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=596df33d673d9d816b60b95088e59a76d845c254;p=platform%2Fkernel%2Flinux-starfive.git

fuse: drop redundant arguments to fuse_perform_write

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