23 fixes in 5 drivers (qla2xxx, ufs, scsi_debug, fcoe, zfcp). The bulk
of the changes are in qla2xxx and ufs and all are mostly small and
definitely don't impact the core.

On Intel Scalable I/O Virtualization (SIOV) enabled platforms, IOMMU
driver is one of the users of IOASIDs. In normal flow, callers will
perform IOASID allocation, bind, unbind, and free in order. However, for
guest SVA, IOASID free could come before unbind as guest is untrusted.

This converts the Direct IO block/bio layer over to use FOLL_PIN pages

Add a new BIO_FOLL_PIN flag to struct bio, whose "short int" flags field

bio page release mechanism matches the page acquisition mechanism.

This reduces, by one, the number of callers of iov_iter_get_pages().
That's helpful because these calls are being audited and converted over
to use iov_iter_pin_user_pages(), where applicable. And this one here is
already known by the caller to be only for ITER_PIPE, so let's just
simplify it now.
pin_user_page() is the FOLL_PIN equivalent of get_page().
This was always a missing piece of the pin/unpin API calls (early

it just wasn't needed. Finally though, now that the Direct IO pieces in

Just fyi for anyone that cares:
A janitorial task for someone might be to use Julia's coccinelle
script below to convert the existing instances of commas that
separate statements into semicolons.
Dear RT Folks,
I'm pleased to announce the 5.4.59-rt36 stable release.
This release is just an update to the new stable 5.4.59 version
and no RT specific changes have been made.
You can get this release via the git tree at:

Critical data structures of security modules are currently not measured.
Therefore an attestation service, for instance, would not be able to
attest whether the security modules are always operating with the policies
and configuration that the system administrator had setup. The policies

For the device-mapper targets to take advantage of IMA's measuring and
quoting abilities, and for enabling remote attestation for device-mapper
targets, device-mapper needs to provide the functionality to
consistently measure target data using ima_measure_critical_data()
function provided by IMA.
There are several device-mapper targets which contribute to verify
the integrity of the mapped devices e.g. dm-integrity, dm-verity,
dm-crypt etc.
But they do not use the capabilities provided by kernel integrity
subsystem (IMA). For instance, the IMA capability that measures several
in-memory
Currently, dm-crypt does not take advantage of IMA measuring
capabilities, and ultimately the benefits of remote attestation.
Measure various dm-crypt constructs by calling various device-mapper
functions - dm_ima_*() that use IMA measuring capabilities. Implement
ima_measure_dm_crypt_data() to
