Move core file code to fs/kernfs/file.c. fs/sysfs/file.c now contains
sysfs kernfs_ops callbacks, sysfs wrappers around kernfs interfaces,
and sysfs_schedule_callback(). The respective declarations in
fs/sysfs/sysfs.h are moved to fs/kernfs/kernfs-internal.h.
This is pure relocation.
v2: Refreshed on top of the v2 of "sysfs, kernfs: prepare read path
for kernfs".
v3: Refreshed on top of the v3 of "sysfs, kernfs: prepare read path
for kernfs".

Move core dir code to fs/kernfs/dir.c. fs/sysfs/dir.c now only
contains sysfs_warn_dup() and sysfs wrappers around kernfs interfaces.
The respective declarations in fs/sysfs/sysfs.h are moved to
fs/kernfs/kernfs-internal.h.
This is pure relocation.
v2: sysfs_symlink_target_lock was mistakenly relocated to kernfs. It
should remain with sysfs. Fixed.

There's nothing sysfs-specific in fs/sysfs/inode.c. Move everything
in it to fs/kernfs/inode.c. The respective declarations in
fs/sysfs/sysfs.h are moved to fs/kernfs/kernfs-internal.h.
This is pure relocation.

Move data structure, constant and basic accessor declarations from
fs/sysfs/sysfs.h to fs/kernfs/kernfs-internal.h. The two files
currently include each other. Once kernfs / sysfs separation is
complete, the cross inclusions will be removed. Inclusion protectors
are added to fs/sysfs/sysfs.h to allow cross-inclusion.
This patch doesn't introduce any functional changes.

Core sysfs implementation will be separated into kernfs so that it can
be used by other non-kobject users.
This patch creates fs/kernfs/ directory and makes boilerplate changes.
kernfs interface will be directly based on sysfs_dirent and its
forward declaration is moved to include/linux/kernfs.h which is
included from include/linux/sysfs.h. sysfs core implementation will
be gradually separated out and moved to kernfs.
This patch doesn't introduce any functional changes.
v2: mount.c added.
