Checkpoint/restart file owner, file-locks and file-lease information. See Documentation/checkpoint/file-locks added by patch 17/17 for design and file-system consistency requirements. Changelog[v4]: - [Oren Laadan, Steven Whitehouse]: Document design and fs consistency requirements. - [Oren Laadan]: For consistency with other such objects, replace the "marker lock" checkpoint with a checkpoint of a count of the file-locks before the first file-lock of each file. Changelog[v3]: - Broke-up C/R of file-leases patches into smaller patches and included them in this set. - Addressed comments from Jamie Lokier, Oren Laadan with help from John Stultz on the computation of time offsets.
