Bug description:
== SRU Hirsute ==
[Impact]
Add support for 5.14 kernels in Hirsute for zfs-linux dkms module.
zfs-linux needs compat changes in order to build against 5.14 kernel
like oem-5.14 in focal:
- Linux-5.12-compat-bio-bi_disk-member-moved.patch
- Linux-5.12-compat-replace-bio_-_io_acct-with-disk_-_.patch
- Linux-5.12-compat-idmapped-mounts.patch
- Linux-5.12-update-bio_max_segs-replaces-BIO_MAX_PAGE.patch
- Remove-iov_iter_advance-for-iter_write.patch
- linux-5.13-compat-bdevops-revalidate_disk-removed.patch
- Linux-5.14-compat-blk_alloc_disk.patch
- Linux-5.14-compat-explicity-assign-set_page_dirty.patch
- Linux-5.14-compat-META.patch
[Test Plan]
Run the ubuntu ZFS regressions tests, these cover smoke testing core
functionality, POSIX fs semantics, subset of xfs tests and all mount
options with file system stress-ng stress tests.
see git://kernel.ubuntu.com/ubuntu/autotest-client/tests/ubuntu_zfs*
tests
[Where problems could occur]
in BIO and block allocation layers in ZFS. These are exercised
extensively by the ZFS regression tests.
The 5.12..5.14 compat options are dkms build time config checks, so
build testing the zfs-dkms package with 5.11 and 5.14 kernels will
ensure these dkms build-time options are exercised.
[Other Info]
These Linux 5.12..5.14 compat patches are in Ubuntu impish and have
had some testing already, so the regression potential is low as these
code paths have already had some exposure to real work loads.
Tested on x86-64 with 5.11 and 5.14 kernels to exercise the build-time
dkms config kernel detection paths. Exercised with the ubuntu zfs
regression tests.
