		109	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		110	in 5.18. What's so attractive about giving a shit about backwards
		111	compatibility - I will never understand.
		112
		113	4.2 Sat Jan 25 01:13:14 CET 2014

		136	as per unix spec.
		137
		138	4.16 Tue Aug 14 05:39:03 CEST 2012

		146	set FIEMAP_EXTENT_LAST on last segment.
		147	- work around linux kernel bug (at least in 3.2): kernel silently
		148	truncates segment count if a file.

		150	to quick overview.
