- Delay the cleanup of interrupted posix lock requests until the user
space result arrives. Previously, the immediate cleanup would lead to
extraneous warnings when the result arrived.
- Tracepoint improvements, e.g. adding the lock resource name.
- Delay the completion of lockspace creation until one full recovery
cycle has completed. This allows more error cases to be returned to
the caller.
- Remove warnings from the locking layer about delayed network replies.
The recently added midcomms warnings are much more useful.
- Begin the process of deprecating two unused lock-timeout-related
features. These features now require enabling via a Kconfig option,
and enabling them triggers deprecation warnings. We expect to remove
the code in v6.2.

The unhold_lkb() function decrements the lock's kref, and
asserts that the ref count was not the final one. Use the
kref_put release function (which should not be called) to
call the assert, rather than doing the assert based on the
kref_put return value. Using kill_lkb() as the release
function doesn't make sense if we only want to assert.

This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option
that must be enabled to use two timeout-related features
that we intend to remove in kernel v6.2. Warnings are
printed if either is enabled and used. Neither has ever
been used as far as we know.
. The DLM_LSFL_TIMEWARN lockspace creation flag will be
removed, along with the associated configfs entry for
setting the timeout. Setting the flag and configfs file
would cause dlm to track how long locks were waiting
for reply messages. After a timeout, a kernel message
would be logged, and a netlink message would be sent
to userspace. Recently, midcomms messages have been
added that produce much better logging about actual
problems with messages. No use has ever been found
for the netlink messages.
. The userspace libdlm API has allowed the DLM_LKF_TIMEOUT
flag with a timeout value to be set in lock requests.
The lock request would be cancelled after the timeout.

Currently the error and info messages handled by exfat_err() and co
are tossed to exfat_msg() function that does nothing but passes the
strings with printk() invocation. Not only that this is more overhead
by the indirect calls, but also this makes harder to extend for the
debug print usage; because of the direct printk() call, you cannot
make it for dynamic debug or without debug like the standard helpers
such as pr_debug() or dev_dbg().
For addressing the problem, this patch replaces exfat_*() macro to
expand to pr_*() directly. Along with it, add the new exfat_debug()
macro that is expanded to pr_debug() (which output can be gracefully
suppressed via dyndbg).

LTP has a test for oversized file path renames and it expects the
return value to be ENAMETOOLONG. However, exfat returns EINVAL
unexpectedly in some cases, hence LTP test fails. The further
investigation indicated that the problem happens only when iocharset
isn't set to utf8.
The difference comes from that, in the case of utf8,
exfat_utf8_to_utf16() returns the error -ENAMETOOLONG directly and
it's treated as the final error code. Meanwhile, on other iocharsets,
exfat_nls_to_ucs2() returns the max path size but it sets
NLS_NAME_OVERLEN to lossy flag instead; the caller side checks only
whether lossy flag is set or not, resulting in always -EINVAL
unconditionally.
This patch aligns the return code for both cases by checking the lossy
flag bit and returning ENAMETOOLONG when NLS_NAME_OVERLEN bit is set.

f2fs_copy_page() is a wrapper around two kmap() + one memcpy() from/to
the mapped pages. It unnecessarily duplicates a kernel API and it makes
use of kmap(), which is being deprecated in favor of kmap_local_page().
Two main problems with kmap(): (1) It comes with an overhead as mapping
space is restricted and protected by a global lock for synchronization and
(2) it also requires global TLB invalidation when the kmap’s pool wraps
and it might block when the mapping space is fully utilized until a slot
becomes available.
With kmap_local_page() the mappings are per thread, CPU local, can take
page faults, and can be called from any context (including interrupts).
It is faster than kmap() in kernels with HIGHMEM enabled. Therefore, its
use in __clone_blkaddrs() is safe and should be preferred.
Delete f2fs_copy_page() and use a plain memcpy_page() in the only one
site calling the removed function. memcpy_page() avoids open coding two
kmap_local_page() + one memcpy() between the two kernel virtual addresses.
