I'm pretty sure that someone got that wrong. The real issue is that xfs is really slow comparatively at deleting *small* files. I did a test just a couple months ago comparing reiser and xfs. xfs was 30x slower. My test was to make a copy of a linux kernel source tree. Then time deleting it. Reiser did it in a couple seconds. xfs took a minute. So xfs is not a good choice to hold your source directories it your a kernel developer.
