Subject: xfs: move xfs_iext_insert tracepoint to report useful information
Git-commit: c54854a437a447a6bb1dcb11f60dd01cef3fa597
Patch-mainline: v4.15-rc5
References: bsc#1095344
Move the tracepoint in xfs_iext_insert to after the point where we've
inserted the extent because otherwise we report stale extent data in
the ftrace output.
