New upstream release 4.5.2.
* Thanks for NMU of package rename. * New upstream release 4.5.2. * Upload using dgit. * Source-only upload. * btrfs-convert should not be included in the initramfs, but should be compiled. Using btrfs-convert is not a trivial operation, and especially not from a minimal shell. Also it is known to fail, and for a sophisticated user it is trivial to include it in the initramfs. Thus won't fix Closes: #801192 * No sponsorship required Closes: #823474 * Add Provides btrfs-tools-udeb to the -progs-udeb package.
