The X-Powers AXP717 PMIC has separate input supply pins for each group
of LDOs, so they are not all using the same DCDC1 input, as described
currently.

Replace the "supply" member of each LDO description with the respective
group supply name, so that the supply dependencies can be correctly
described in the devicetree.

Also fix two off-by-ones in the regulator macros, after some double
checking the numbers against the datasheet. This uncovered a bug in the
datasheet: add a comment to document this.

NFSD: grab nfsd_mutex in nfsd_nl_rpc_status_get_dumpit()
nfsd: fix oops when reading pool_stats before server is started

The patch 15a6af94a277 ("spi: Increase imx51 ecspi burst length based
on transfer length") increased the burst length calculation in
mx51_ecspi_prepare_transfer() to be based on the transfer length.

This breaks HW CS + SPI_CS_WORD support which was added in
6e95b23a5b2d ("spi: imx: Implement support for CS_WORD") and transfers
with bits-per-word != 8, 16, 32.

SPI_CS_WORD means the CS should be toggled after each word. The
implementation in the imx-spi driver relies on the fact that the HW CS
is toggled automatically by the controller after each burst length
number of bits. Setting the burst length to the number of bits of the
_whole_ message breaks this use case.

Further the patch 15a6af94a277 ("spi: Increase imx51 ecspi burst
length based on transfer length") claims to optimize the transfers.
But even without this patch, on modern spi-imx controllers with
"dynamic_burst = true" (imx51, imx6 and newer), the transfers are
already optimized, i.e. the burst length is dynamically adjusted in
spi_imx_push() to avoid the pause between the SPI bursts. This has
been confirmed by a scope measurement on an imx6d.

Subsequent Patches tried to fix these and other problems:

- 5f66db08cbd3 ("spi: imx: Take in account bits per word instead of assuming 8-bits")
- e9b220aeacf1 ("spi: spi-imx: correctly configure burst length when using dma")
- c712c05e46c8 ("spi: imx: fix the burst length at DMA mode and CPU mode")
- cf6d79a0f576 ("spi: spi-imx: fix off-by-one in mx51 CPU mode burst length")

but the HW CS + SPI_CS_WORD use case is still broken.

To fix the problems revert the burst size calculation in
mx51_ecspi_prepare_transfer() back to the original form, before
15a6af94a277 ("spi: Increase imx51 ecspi burst length based on
transfer length") was applied.

While adding a SPI device, the SPI core ensures that multiple logical CS
doesn't map to the same physical CS. For example, spi->chip_select[0] !=
spi->chip_select[1] and so forth. However, unlike the SPI master, the SPI
slave doesn't have the list of chip selects, this leads to probe failure
when the SPI controller is configured as slave. Update the
__spi_add_device() function to perform this check only if the SPI
controller is configured as master.

"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

And occurs when the the inode precommit handlers is attempt to look
up the inode cluster buffer to attach the inode for writeback.

The trail of logic that I can reconstruct is as follows.

1. the inode is clean when inodegc runs, so it is not
attached to a cluster buffer when precommit runs.

2. #1 implies the inode cluster buffer may be clean and not
pinned by dirty inodes when inodegc runs.

3. #2 implies that the inode cluster buffer can be reclaimed
by memory pressure at any time.

4. The assert failure implies that the cluster buffer was
attached to the transaction, but not marked done. It had
been accessed earlier in the transaction, but not marked
done.

5. #4 implies the cluster buffer has been invalidated (i.e.
marked stale).

6. #5 implies that the inode cluster buffer was instantiated
uninitialised in the transaction in xfs_ifree_cluster(),
which only instantiates the buffers to invalidate them
and never marks them as done.

Given factors 1-3, this issue is highly dependent on timing and
environmental factors. Hence the issue can be very difficult to
reproduce in some situations, but highly reliable in others. Luis
has an environment where it can be reproduced easily by g/531 but,
OTOH, I've reproduced it only once in ~2000 cycles of g/531.

I think the fix is to have xfs_ifree_cluster() set the XBF_DONE flag
on the cluster buffers, even though they may not be initialised. The
reasons why I think this is safe are:

1. A buffer cache lookup hit on a XBF_STALE buffer will
clear the XBF_DONE flag. Hence all future users of the
buffer know they have to re-initialise the contents
before use and mark it done themselves.

2. xfs_trans_binval() sets the XFS_BLI_STALE flag, which
means the buffer remains locked until the journal commit
completes and the buffer is unpinned. Hence once marked
XBF_STALE/XFS_BLI_STALE by xfs_ifree_cluster(), the only
context that can access the freed buffer is the currently
running transaction.

3. #2 implies that future buffer lookups in the currently
running transaction will hit the transaction match code
and not the buffer cache. Hence XBF_STALE and
XFS_BLI_STALE will not be cleared unless the transaction
initialises and logs the buffer with valid contents
again. At which point, the buffer will be marked marked
XBF_DONE again, so having XBF_DONE already set on the
stale buffer is a moot point.

4. #2 also implies that any concurrent access to that
cluster buffer will block waiting on the buffer lock
until the inode cluster has been fully freed and is no
longer an active inode cluster buffer.

5. #4 + #1 means that any future user of the disk range of
that buffer will always see the range of disk blocks
covered by the cluster buffer as not done, and hence must
initialise the contents themselves.

6. Setting XBF_DONE in xfs_ifree_cluster() then means the
unlinked inode precommit code will see a XBF_DONE buffer
from the transaction match as it expects. It can then
attach the stale but newly dirtied inode to the stale
but newly dirtied cluster buffer without unexpected
failures. The stale buffer will then sail through the
journal and do the right thing with the attached stale
inode during unpin.

Hence the fix is just one line of extra code. The explanation of
why we have to set XBF_DONE in xfs_ifree_cluster, OTOH, is long and
complex....
