Pull vfs 'protection info' updates from Christian Brauner:
"This adds the new FS_IOC_GETLBMD_CAP ioctl() to query metadata and
protection info (PI) capabilities. This ioctl returns information
about the files integrity profile. This is useful for userspace
applications to understand a files end-to-end data protection support
and configure the I/O accordingly.
For now this interface is only supported by block devices. However the
design and placement of this ioctl in generic FS ioctl space allows us
to extend it to work over files as well. This maybe useful when
filesystems start supporting PI-aware layouts.
A new structure struct logical_block_metadata_cap is introduced, which
contains the following fields:
- lbmd_flags:
bitmask of logical block metadata capability flags
- lbmd_interval:
the amount of data described by each unit of logical block metadata
- lbmd_size:
size in bytes of the logical block metadata associated with each
interval
- lbmd_opaque_size:
size in bytes of the opaque block tag associated with each interval
- lbmd_opaque_offset:
offset in bytes of the opaque block tag within the logical block
metadata
- lbmd_pi_size:
size in bytes of the T10 PI tuple associated with each interval
- lbmd_pi_offset:
offset in bytes of T10 PI tuple within the logical block metadata
- lbmd_pi_guard_tag_type:
T10 PI guard tag type
- lbmd_pi_app_tag_size:
size in bytes of the T10 PI application tag
- lbmd_pi_ref_tag_size:
size in bytes of the T10 PI reference tag
- lbmd_pi_storage_tag_size:
size in bytes of the T10 PI storage tag
The internal logic to fetch the capability is encapsulated in a helper
function blk_get_meta_cap(), which uses the blk_integrity profile
associated with the device. The ioctl returns -EOPNOTSUPP, if
CONFIG_BLK_DEV_INTEGRITY is not enabled"

Pull fallocate updates from Christian Brauner:
"fallocate() currently supports creating preallocated files
efficiently. However, on most filesystems fallocate() will preallocate
blocks in an unwriten state even if FALLOC_FL_ZERO_RANGE is specified.
The extent state must later be converted to a written state when the
user writes data into this range, which can trigger numerous metadata
changes and journal I/O. This may leads to significant write
amplification and performance degradation in synchronous write mode.
At the moment, the only method to avoid this is to create an empty
file and write zero data into it (for example, using 'dd' with a large
block size). However, this method is slow and consumes a considerable
amount of disk bandwidth.
Now that more and more flash-based storage devices are available it is
possible to efficiently write zeros to SSDs using the unmap write
zeroes command if the devices do not write physical zeroes to the
media.
For example, if SCSI SSDs support the UMMAP bit or NVMe SSDs support
the DEAC bit[1], the write zeroes command does not write actual data
to the device, instead, NVMe converts the zeroed range to a
deallocated state, which works fast and consumes almost no disk write
bandwidth.
This series implements the BLK_FEAT_WRITE_ZEROES_UNMAP feature and
BLK_FLAG_WRITE_ZEROES_UNMAP_DISABLED flag for SCSI, NVMe and
device-mapper drivers, and add the FALLOC_FL_WRITE_ZEROES and
STATX_ATTR_WRITE_ZEROES_UNMAP support for ext4 and raw bdev devices.
fallocate() is subsequently extended with the FALLOC_FL_WRITE_ZEROES
flag. FALLOC_FL_WRITE_ZEROES zeroes a specified file range in such a
way that subsequent writes to that range do not require further
changes to the file mapping metadata. This flag is beneficial for
subsequent pure overwriting within this range, as it can save on block
allocation and, consequently, significant metadata changes"

ext4: add FALLOC_FL_WRITE_ZEROES support

In case of an ib_fast_reg_mr allocation failure during iSER setup, the
machine hits a panic because iscsi_conn->dd_data is initialized
unconditionally, even when no memory is allocated (dd_size == 0). This
leads invalid pointer dereference during connection teardown.
Fix by setting iscsi_conn->dd_data only if memory is actually allocated.

Introduce struct ata_reset_operations to aggregate in a single structure
the definitions of the 4 reset methods (prereset, softreset, hardreset
and postreset) for a port. This new structure is used in struct ata_port
to define the reset methods for a regular port (reset field) and for a
port-multiplier port (pmp_reset field). A pointer to either of these
fields replaces the 4 reset method arguments passed to ata_eh_recover()
and ata_eh_reset().
The definition of the reset methods for all drivers is changed to use
the reset and pmp_reset fields in struct ata_port_operations.
A large number of files is modifed, but no functional changes are
introduced.

When the bfad_im_probe() function fails during initialization, the memory
pointed to by bfad->im is freed without setting bfad->im to NULL.
Subsequently, during driver uninstallation, when the state machine enters
the bfad_sm_stopping state and calls the bfad_im_probe_undo() function,
it attempts to free the memory pointed to by bfad->im again, thereby
triggering a double-free vulnerability.
Set bfad->im to NULL if probing fails.

The calculation of the upper limit for queues does not depend solely on
the number of possible CPUs; for example, the isolcpus kernel
command-line option must also be considered.
To account for this, the block layer provides a helper function to
retrieve the maximum number of queues. Use it to set an appropriate
upper queue number limit.

Introduce a new pi_tuple_size field in struct blk_integrity to
explicitly represent the size (in bytes) of the protection information
(PI) tuple. This is a prep patch.
Add validation in blk_validate_integrity_limits() to ensure that
pi size matches the expected size for known checksum types and never
exceeds the pi_tuple_size.

The virt_boundary_mask limit requires an unlimited max_segment_size for
bio splitting to not corrupt data. Historically, the block layer tried
to validate this, although the check was half-hearted until the addition
of the atomic queue limits API. The full blown check then triggered
issues with stacked devices incorrectly inheriting limits such as the
virt boundary and got disabled in commit b561ea56a264 ("block: allow
device to have both virt_boundary_mask and max segment size") instead of
fixing the issue properly.
Ensure that the SCSI mid layer doesn't set the default low
max_segment_size limit for this case, and check for invalid
max_segment_size values in the host template, similar to the original
block layer check given that SCSI devices can't be stacked.
This fixes reported data corruption on storvsc, although as far as I can
tell storvsc always failed to properly set the max_segment_size limit as
the SCSI APIs historically applied that when setting up the host, while
storvsc only set the virt_boundary_mask when configuring the scsi_device.

sd_read_block_limits_ext() currently assumes that vpd->len excludes the
size of the page header. However, vpd->len describes the size of the entire
VPD page, therefore the sanity check is incorrect.
In practice this is not really a problem since we don't attach VPD
pages unless they actually report data trailing the header. But fix
the length check regardless.
This issue was identified by Wukong-Agent (formerly Tencent Woodpecker), a
code security AI agent, through static code analysis.

Add pm80xx_fatal_error_uevent_emit() which is called when the pm80xx
driver encouters a fatal error. The uevent has the following additional
custom key/value pair sets:
- DRIVER: driver name, pm80xx in this case
- HBA_NUM: the scsi host id of the device
- EVENT_TYPE: to indicate a fatal error
- REPORTED_BY: either driver or firmware
The uevent is anchored to the kernel object that represents the SCSI
controller, which includes other useful core variables, such as, ACTION,
DEVPATH, SUBSYSTEM, and more.
The fatal_error_uevent_emit() function is called when the controller
fatal error state changes. Since this doesn't happen often for a
specific SCSI host, there is no worries of a uevent storm.

During rmmod, all ndlp objects are cleaned up and marked with the
NLP_DROPPED flag indicating that an ndlp object is currently being
released. Thus, if an RSCN is received during driver unload, then
walking the fc_nodes list to process the RSCN is unnecessary because the
ndlp objects are very shortly going to be released.

If a call to lpfc_sli4_read_rev() from lpfc_sli4_hba_setup() fails, the
resultant cleanup routine lpfc_sli4_vport_delete_fcp_xri_aborted() may
occur before sli4_hba.hdwqs are allocated. This may result in a null
pointer dereference when attempting to take the abts_io_buf_list_lock for
