X-Git-Tag: v4.15.0-rc1~79^2~3

xfs: move xfs_iext_insert tracepoint to report useful information

Source kernel commit: c54854a437a447a6bb1dcb11f60dd01cef3fa597

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.
