i2c: designware: Invoke runtime suspend on quick slave re-registration
Replaced pm_runtime_put() with pm_runtime_put_sync_suspend() to ensure
the runtime suspend is invoked immediately when unregistering a slave.
This prevents a race condition where suspend was skipped when
unregistering and registering slave in quick succession.
For example, consider the rapid sequence of
`delete_device -> new_device -> delete_device -> new_device`.
In this sequence, it is observed that the dw_i2c_plat_runtime_suspend()
might not be invoked after `delete_device` operation.
This is because after `delete_device` operation, when the
pm_runtime_put() is about to trigger suspend, the following `new_device`
operation might race and cancel the suspend.
If that happens, during the `new_device` operation,
dw_i2c_plat_runtime_resume() is skipped (since there was no suspend), which
means `i_dev->init()`, i.e. i2c_dw_init_slave(), is skipped.
Since i2c_dw_init_slave() is skipped, i2c_dw_configure_fifo_slave() is
skipped too, which leaves `DW_IC_INTR_MASK` unconfigured. If we inspect
the interrupt mask register using devmem, it will show as zero.

i2c-mlxbf: Improve I2C bus timing configuration
Update the I2C bus timing configuration on BlueField to match the

I2C block read failures were found on BlueField 3 during communication

Testing showed that these failures were caused by the I2C transaction

i2c: octeon: add block-mode i2c operations
Add functions to perform block read and write operations. This applies
for cases where the requested operation is for >8 bytes of data.
When not using the block mode transfer, the driver will attempt a series
of 8 byte i2c operations until it reaches the desired total. For
example, for a 40 byte request the driver will complete 5 separate
transactions. This results in large transactions taking a significant
amount of time to process.
Add block mode such that the driver can request larger transactions, up
to 1024 bytes per transfer.
Many aspects of the block mode transfer is common with the regular 8
byte operations. Use generic functions for parts of the message
construction and sending the message. The key difference for the block
mode is the usage of separate FIFO buffer to store data.
Write to this buffer in the case of a write (before command send).
Read from this buffer in the case of a read (after command send).
Data is written into this buffer by placing data into the MSB onwards.
This means the bottom 8 bits of the data will match the top 8 bits, and
so on and so forth.
Set specific bits in message for block mode, enable block mode transfers
from global i2c management registers, construct message, send message,
read or write from FIFO buffer as required.
The block-mode transactions result in a significant speed increase in
large i2c requests.

NFS: Avoid flushing data while holding directory locks in nfs_rename()
The Linux client assumes that all filehandles are non-volatile for
renames within the same directory (otherwise sillyrename cannot work).
However, the existence of the Linux 'subtree_check' export option has
meant that nfs_rename() has always assumed it needs to flush writes
before attempting to rename.
Since NFSv4 does allow the client to query whether or not the server
exhibits this behaviour, and since knfsd does actually set the
appropriate flag when 'subtree_check' is enabled on an export, it
should be OK to optimise away the write flushing behaviour in the cases
where it is clearly not needed.

NFSv4/pnfs: Reset the layout state after a layoutreturn
If there are still layout segments in the layout plh_return_lsegs list
after a layout return, we should be resetting the state to ensure they
eventually get returned as well.
