Merge tag 'trace-ring-buffer-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ring-buffer updates from Steven Rostedt
- Do not invalidate entire buffer for invalid sub-buffers
For the persistent ring buffer, if one sub-buffer is found to be
invalid, it invalidates the entire per CPU ring buffer. This can lose
a lot of valuable data if there's some corruption with the writes to
the buffer not syncing properly on a hard crash. Instead, if a
sub-buffer is found to be invalid, simply zero it out and mark it for
"missed events".
When the persistent ring buffer is read and a sub-buffer that was
cleared due to being invalid on boot up is discovered, the output
will show "[LOST EVENTS]" to let the user know that events were
missing at that location. Displaying the events from valid buffers
can still be useful.

Pull tracing updates from Steven Rostedt:
- Remove a redundant IS_ERR() check
trace_pipe_open() already checks for IS_ERR() and does it again in
the return path. Remove the return check.
- Export seq_buf_putmem_hex() to allow kunit tests against them
To add Kunit tests on seq_buf_putmem_hex(), it needs to be exported.
- Replace strcat() and strcpy() with seq_buf() logic
The code for synthetic events uses a series of strcat() and strcpy()
which can be error prone. Replace them with seq_buf() logic that does
all the necessary bound checking.

"Jeff Layton wired up netlink upcalls for the auth.unix.ip and
auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh caches
in NFSD. The new kernel-user API is more extensible and lays the
groundwork for retiring the old pipe interface.
The default NFS r/w block size rises to 4MB on hosts with at least
16GB of RAM, reducing per-RPC overhead on fast networks. Smaller
machines keep their previously computed default, and the value remains
tunable through /proc/fs/nfsd/max_block_size.
Chuck Lever converted the server's RPCSEC GSS Kerberos code to the
kernel's shared crypto/krb5 library. The conversion retires and
removes SunRPC's bespoke implementation of Kerberos v5, but keeps
RPCSEC GSS-API.
