This reverts commit e6595224464b692ddae193d783402130d1625147.
These kinds of patches are only making the code worse.
Compilers don't care about the unnecessary check, but removing it makes
the code less obvious to a human. The declaration of 'len' is more than
80 lines earlier, so a human won't easily see that 'len' is of an
unsigned type, so to a human the range check that checks against zero is
much more explicit and obvious.
Any tool that complains about a range check like this just because the
variable is unsigned is actively detrimental, and should be ignored.

tasklet; however, it's marked deprecated and has some design flaws. To
replace tasklets, BH workqueue support was recently added. A BH workqueue
behaves similarly to regular workqueues except that the queued work items
are executed in the BH context.

The kernel FIFO queue has a couple issues. The biggest issue is that
it causes extra latency in a path that can be used in real-time tasks,
such as communication with real-time remote processors.
The whole FIFO idea itself looks to be a leftover from before the
unified mailbox framework. The current mailbox framework expects
mbox_chan_received_data() to be called with data immediately as it
arrives. Remove the FIFO and pass the messages to the mailbox
framework directly as part of a threaded IRQ handler.

It is much more clear to check if the hardware FIFO is full and return
EBUSY if true. This allows us to also remove one level of indention
from the core of this function. It also makes the similarities between
omap_mbox_chan_send_noirq() and omap_mbox_chan_send() more obvious.

Signed-off-by: Jassi Brar <jassisinghbrar@gmail.com>
This function only checks if mbox_chan *chan is not NULL, but that cannot
be the case and if it was returning NULL which is not later checked
doesn't save us from this. The second check for chan->con_priv is
completely redundant as if it was NULL we would return NULL just the
same. Simply dereference con_priv directly and remove this function.

The driver stores a list of omap_mbox structs so it can later use it to
lookup the mailbox names in of_xlate. This same information is already
available in the mbox_controller passed into of_xlate. Simply use that
data and remove the extra allocation and storage of the omap_mbox list.

The mbox_controller struct is only needed in the probe function. Make
it a local variable instead of storing a copy in omap_mbox_device
to simplify that struct.

Currently the driver loops through all mailbox child nodes twice, once
to read in data from each node, and again to make use of this data.
Instead read the data and make use of it in one pass. This removes
the need for several temporary data structures and reduces the
complexity of this main loop in probe.

The driver currently creates a new device class "mbox". Then for each
mailbox adds a device to that class. This class provides no file
operations provided for any userspace users of this device class.
It may have been extended to be functional in our vendor tree at
some point, but that is not the case anymore, nor does it matter
for the upstream tree.
Remove this device class and related functions and variables.
This also allows us to switch to module_platform_driver() as
there is nothing left to do in module_init().

The type of message sent using omap-mailbox is always u32. The definition
of mbox_msg_t is uintptr_t which is wrong as that type changes based on
the architecture (32bit vs 64bit). This type should have been defined as
u32. Instead of making that change here, simply remove the header usage
and fix the last couple users of the same in this driver.

Bitops API is the very basic, and it's widely used by the kernel. But
corresponding files are not maintained.
Bitmaps actively use bit operations, and big share of bitops material
already moves through the bitmap branch.
I would like to take a closer look to bitops.
This patch creates a BITOPS API record in the MAINTAINERS, and adds
Rasmus as a reviewer, and myself as a maintainer of those files.

- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata in
memory.
The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.
- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take too
many for lockdep to track, and it's not necessary since we have a
cycle detector.
- Trigger improvements that are prep work for online fsck
- BTREE_TRIGGER_check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.
- bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.
- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.
- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.
- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.
- Safety fixes for devices references: this is a big series that changes
almost all device lookups to properly check if the device exists and
take a reference to it.
Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid methods,
but this was incorrect because it meant device removal relied on
accounting being correct to not leave keys pointing to invalid
devices, and that's not something we can assume.
Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.
- The allocator now prefers not to expand the new
member_info.btree_allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).
- New coding style document, which among other things talks about the

- Lucas Stach has provided some page-mapping
cleanup/consolidation/maintainability work in the series "mm/treewide:
Remove pXd_huge() API".

Suren Baghdasaryan have contributed a means of determining (via
/proc/allocinfo) whereabouts in the kernel memory is being allocated:
number of calls and amount of memory.

patches" which does a number of rather unrelated things, but in largely
similar code sites.

Song has optimized pagecache insertion, yielding ~10% performance
improvement in one test.

This is a light release containing mostly optimizations, code clean-
ups, and minor bug fixes. This development cycle has focused on non-
upstream kernel work:
1. Continuing to build upstream CI for NFSD, based on kdevops
2. Backporting NFSD filecache-related fixes to selected LTS kernels
One notable new feature in v6.10 NFSD is the addition of a new
netlink protocol dedicated to configuring NFSD. A new user space
tool, nfsdctl, is to be added to nfs-utils. Lots more to come here.
As always I am very grateful to NFSD contributors, reviewers,
testers, and bug reporters who participated during this cycle.
