[$] The 5.6 merge window opens
As of this writing, 4,726 non-merge changesets have been pulled into the
mainline repository for the 5.6 development cycle. That is a relatively
slow start by contemporary kernel standards, but it still is enough to
bring a number of new features, some of which have been pending for years,
into the mainline. Read on for a summary of the changes pulled in the
early part of the 5.6 merge window.
