Dockerfile*: bump devmapper library version Let's use latest lvm2 sources to compile the libdevmapper library. Initial reason for compiling devmapper lib from sources was a need to have the static version of the library at hand, in order to build the static dockerd, but note that the same headers/solib are used for dynamic build (dynbinary) as well. The reason for this patch is to enable the deferral removal feature. The supplied devmapper library (and headers) are too old, lacking the needed functions, so the daemon is built with 'libdm_no_deferred_remove' build tag (see the check in hack/make.sh). Because of this, even if the kernel dm driver is perfectly able to support the feature, it can not be used. For more details and background story, see [1]. Surely, one can't just change the version number. While at it: - improve the comments; - remove obsoleted URLs; - remove s390 and ppc configure updates that are no longer needed; - use pkg-config instead of hardcoding the flags (newer lib added some more dependencies); [1] https://github.com/moby/moby/issues/34298 Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com> 2017-08-01 20:29:29 -04:00			`// +build linux,cgo,static_build`
