cc102aa246 jbd2: avoid memleak in jbd2_journal_write_metadata_buffer
The new_bh is from alloc_buffer_head, we should call free_buffer_head to
free it in error case.

8dc9c3da79 ext4: fix uninitialized variable in ext4_inlinedir_to_tree
Syzbot has found an uninit-value bug in ext4_inlinedir_to_tree

This error happens because ext4_inlinedir_to_tree does not
handle the case when ext4fs_dirhash returns an error

This can be avoided by checking the return value of ext4fs_dirhash
and propagating the error,
similar to how it's done with ext4_htree_store_dirent

c3de9b572f bcachefs fixes for 6.10-rc5
Lots of (mostly boring) fixes for syzbot bugs and rare(r) CI bugs.
 
 The LRU_TIME_BITS fix was slightly more involved; we only have 48 bits
 for the LRU position (we would prefer 64), so wraparound is possible for
 the cached data LRUs on a filesystem that has done sufficient
 (petabytes) reads; this is now handled.
 
 One notable user reported bugfix, where we were forgetting to correctly
 set the bucket data type, which should have been BCH_DATA_need_gc_gens
 instead of BCH_DATA_free; this was causing us to go emergency read-only
 on a filesystem that had seen heavy enough use to see bucket gen
 wraparoud.
 
 We're now starting to fix simple (safe) errors without requiring user
 intervention - i.e. a small incremental step towards full self healing.
 This is currently limited to just certain allocation information
 counters, and the error is still logged in the superblock; see that
 patch for more information. ("bcachefs: Fix safe errors by default").

dab8f9f0fe pwm: stm32: Fix calculation of prescaler
A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.

One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to

	ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301

This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.

Fix the calculation accordingly and adapt the comment to match the new
algorithm.

With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.

fbe7ef3f2f Thermal control fixes for 6.10-rc5
- Remove the filtered mode for mt8188 from lvts_thermal as it is not
    supported on this platform and fail the lvts_thermal initialization
    when the golden temperature is zero as that means the efuse data is
    not correctly set (Julien Panis).
 
  - Update the processor_thermal part of the Intel int340x driver to
    support shared interrupts as the processor thermal device interrupt
    may in fact be shared with PCI devices (Srinivas Pandruvada).
 
  - Synchronize the suspend-prepare and post-suspend actions of the
    thermal PM notifier to avoid a destructive race condition and
    change the priority of that notifier to the minimum to avoid
    interference between the work items spawned by it and the other
    PM notifiers during system resume (Rafael Wysocki).

If period_ns is small, prd might well become 0. Catch that case because
otherwise with

	regmap_write(priv->regmap, TIM_ARR, prd - 1);

a few lines down quite a big period is configured.

Incorrect bucket state transition in the discard path; when incrementing
a bucket's generation number that had already been discarded, we were
forgetting to check if it should be need_gc_gens, not free.

This was caught by the .invalid checks in the transaction commit path,
causing us to go emergency read only.
