Subject: xfs: remove dfops parameter from ifree call stack
X-Git-Tag: v4.19~337^2~133
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0e0417f3e54668cec9f677850130e6fbb64edcf2;p=platform%2Fkernel%2Flinux-rpi.git

xfs: remove dfops parameter from ifree call stack

The inode free callchain starting in xfs_inactive_ifree() already
associates its dfops with the transaction. It still passes the dfops
on the stack down through xfs_difree_inobt(), however.

Clean up the call stack and reference dfops directly from the
transaction. This patch does not change behavior.
