Add support for Dosilicon DS35Q1GA (3.3V) and DS35M1GA (1.8V) SPI NAND.
These are 1Gbit (128MB) devices with:
- 2048 byte pages + 64 byte OOB
- 64 pages per block, 1024 blocks
- On-die 4-bit ECC per 512 byte sector
The 64-byte OOB area is divided into 4 segments of 16 bytes, with each
segment containing 8 bytes of user data (M2+M1) and 8 bytes of ECC
parity (R1). This provides 30 bytes of usable OOB space after reserving
2 bytes for the bad block marker.
Tested on Genexis Platinum 4410 (EcoNet EN751221) by writing known
patterns to OOB and verifying ECC parity placement in R1 regions.

Pull shmem rename fixes from Al Viro:
"A couple of shmem rename fixes - recent regression from tree-in-dcache
series and older breakage from stable directory offsets stuff"
* tag 'pull-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
shmem: fix recovery on rename failures
shmem_whiteout(): fix regression from tree-in-dcache series
|
|
maple_tree insertions can fail if we are seriously short on memory;
simple_offset_rename() does not recover well if it runs into that.
The same goes for simple_offset_rename_exchange().
Moreover, shmem_whiteout() expects that if it succeeds, the caller will
progress to d_move(), i.e. that shmem_rename2() won't fail past the
successful call of shmem_whiteout().
Not hard to fix, fortunately - mtree_store() can't fail if the index we
are trying to store into is already present in the tree as a singleton.
For simple_offset_rename_exchange() that's enough - we just need to be
careful about the order of operations.
For simple_offset_rename() solution is to preinsert the target into the
tree for new_dir; the rest can be done without any potentially failing
operations.
That preinsertion has to be done in shmem_rename2() rather than in
simple_offset_rename() itself - otherwise we'd need to deal with the
possibility of failure after successful shmem_whiteout().

The Renesas RZ/T2H (R9A09G077) and Renesas RZ/N2H (R9A09G087) SoCs have an
Interrupt Controller (ICU) that supports interrupts from external pins IRQ0
to IRQ15, and SEI, and software-triggered interrupts INTCPU0 to INTCPU15.
INTCPU0 to INTCPU13, IRQ0 to IRQ13 are non-safety interrupts, while
INTCPU14, INTCPU15, IRQ14, IRQ15 and SEI are safety interrupts, and are
exposed via a separate register space.

Add infrastructure to redirect interrupt handler execution to a
different CPU when the current CPU is not part of the interrupt's CPU
affinity mask.
This is primarily aimed at (de)multiplexed interrupts, where the child
interrupt handler runs in the context of the parent interrupt handler,
and therefore CPU affinity control for the child interrupt is typically
not available.
With the new infrastructure, the child interrupt is allowed to freely
change its affinity setting, independently of the parent. If the
interrupt handler happens to be triggered on an "incompatible" CPU (a
CPU that's not part of the child interrupt's affinity mask), the handler
is redirected and runs in IRQ work context on a "compatible" CPU.
No functional change is being made to any existing irqchip driver, and
irqchip drivers must be explicitly modified to use the newly added
infrastructure to support interrupt redirection.

With the IRQ timing stuff being gone, there is no need to specify a flag
when requesting a percpu interrupt. Not only IRQF_TIMER was the only flag
(set of flags actually) allowed, but nobody ever passed it.
Get rid of __request_percpu_irq(), which was only getting 0 as flags, and
promote request_percpu_irq_affinity() as its replacement.

New network transport protocols want NIC drivers to get hardware timestamps
of all incoming packets, and possibly all outgoing packets.
One example is the upcoming 'Swift congestion control' which is used by TCP
transport and is the primary need for timecounter_cyc2time(). This means
timecounter_cyc2time() can be called more than 100 million times per second
on a busy server.
Inlining timecounter_cyc2time() brings a 12% improvement on a UDP receive
stress test on a 100Gbit NIC.
Note that FDO, LTO, PGO are unable to magically help for this case,
presumably because NIC drivers are almost exclusively shipped as modules.
Add an unlikely() around the cc_cyc2ns_backwards() case, even if FDO (when
used) is able to take care of this optimization.

Requesting a delegation on a file from the userland fcntl() interface
currently succeeds when there are conflicting opens present.
This is because the lease handling code ignores conflicting opens for
FL_LAYOUT and FL_DELEG leases. This was a hack put in place long ago,
because nfsd already checks for conflicts in its own way. The kernel
needs to perform this check for userland delegations the same way it is
done for leases, however.
Make this dependent on the lease_manager by adding a new
->lm_open_conflict() lease_manager operation and have
generic_add_lease() call that instead of check_conflicting_open().
Morph check_conflicting_open() into a ->lm_open_conflict() op that is
only called for userland leases/delegations. Set the
->lm_open_conflict() operations for nfsd to trivial functions that
always return 0.

Zhang Yi points out that the dynamic folio_batch allocation in
iomap_fill_dirty_folios() is problematic for the ext4 on iomap work
that is under development because it doesn't sufficiently handle the
allocation failure case (by allowing a retry, for example). We've
also seen lockdep (via syzbot) complain recently about the scope of
the allocation.
The dynamic allocation was initially added for simplicity and to
help indicate whether the batch was used or not by the calling fs.
To address these issues, put the batch on the stack of
iomap_zero_range() and use a flag to control whether the batch
should be used in the iomap folio lookup path. This keeps things
simple and eliminates allocation issues with lockdep and for ext4 on
iomap.
While here, also clean up the fill helper signature to be more
consistent with the underlying filemap helper. Pass through the
return value of the filemap helper (folio count) and update the
lookup offset via an out param.

Opening and closing an inode dirties the ->i_readcount field.
Depending on the alignment of the inode, it may happen to false-share
with other fields loaded both for both operations to various extent.
This notably concerns the ->i_flctx field.
Since most inodes don't have the field populated, this bit can be managed
with a flag in ->i_opflags instead which bypasses the problem.
Here are results I obtained while opening a file read-only in a loop
with 24 cores doing the work on Sapphire Rapids. Utilizing the flag as
opposed to reading ->i_flctx field was toggled at runtime as the benchmark
was running, to make sure both results come from the same alignment.

before: 3284313
after: 3518711 (+7%)

Or to put it differently, this varies wildly depending on how (un)lucky
you get.
The primary bottleneck before and after is the avoidable lockref trip in
do_dentry_open().

While knfsd offers combined exclusive create and open results to clients,
on some filesystems those results may not be atomic. This behavior can be
observed. For example, an open O_CREAT with mode 0 will succeed in creating
the file but unexpectedly return -EACCES from vfs_open().
Additionally reducing the number of remote RPC calls required for O_CREAT
on network filesystem provides a performance benefit in the open path.
Teach knfsd's helper dentry_create() to use atomic_open() for filesystems
that support it. The previously const @path is passed up to atomic_open()
and may be modified depending on whether an existing entry was found or if
the atomic_open() returned an error and consumed the passed-in dentry.

Introduce a bpf_has_frame_pointer() helper that unwinders can call to
determine whether a given instruction pointer is within the valid frame
pointer region of a BPF JIT program or trampoline (i.e., after the
prologue, before the epilogue).
This will enable livepatch (with the ORC unwinder) to reliably unwind
through BPF JIT frames.

Add a cond_lock annotation for lockref_put_or_lock to make sparse
happy with using it. Note that for this the return value has to be
double-inverted as the return value convention of lockref_put_or_lock
is inverted compared to _trylock conventions expected by __cond_lock,
as lockref_put_or_lock returns true when it did not need to take the
lock.
