The rest of core infrastructure; no new syscalls in that pile,
but the old parts are switched to new infrastructure. At that point
conversions of individual filesystems can happen independently; some
are done here (afs, cgroup, procfs, etc.), there's also a large series
outside of that pile dealing with NFS (quite a bit of option-parsing
stuff is getting used there - it's one of the most convoluted
filesystems in terms of mount-related logics), but NFS bits are
the next cycle fodder.
It got seriously simplified since the last cycle; documentation is
probably the weakest bit at the moment - I considered dropping the
commit introducing Documentation/filesystems/mount_api.txt (cutting
the size increase by quarter ;-), but decided that it would be better
to fix it up after -rc1 instead.
That pile allows to do followup work in independent branches,
which should make life much easier for the next cycle. fs/super.c
size increase is unpleasant; there's a followup series that allows to
shrink it considerably, but I decided to leave that until the next
cycle.
Two trivial conflicts (fs/Makefile and include/linux/kernfs.h),
both as straighforward as it gets. Sat in -next for weeks; the only
change after it went there had been the removal of rather obnoxious
forest of macros in fs_parser.h - with unchanged cpp output.
The following changes since commit 35ac1184244f1329783e1d897f74926d8bb1103a:
cgroup: saner refcounting for cgroup_root (2019-01-17 11:53:02 -0500)

afs: Use fs_context to pass parameters over automount (2019-02-28 03:29:39 -0500)
----------------------------------------------------------------
Al Viro (19):
kill kernfs_pin_sb()
separate copying and locking mount tree on cross-userns copies
saner handling of temporary namespaces
new helpers: vfs_create_mount(), fc_mount()

vfs_get_tree(): evict the call of security_sb_kern_mount()
fs_context flavour for submounts
introduce fs_context methods
convenience helpers: vfs_get_super() and sget_fc()
introduce cloning of fs_context
cgroup: start switching to fs_context
cgroup: fold cgroup1_mount() into cgroup1_get_tree()
cgroup: take options parsing into ->parse_monolithic()
cgroup1: switch to option-by-option parsing
cgroup2: switch to option-by-option parsing
cgroup: stash cgroup_root reference into cgroup_fs_context
cgroup_do_mount(): massage calling conventions
cgroup1_get_tree(): separate "get cgroup_root to use" into a separate helper
