Motivation and Context

Proposed patchset for zfs-2.1.16

Description

The EL 5.14.0-503.11.1.el9_5.x86_64 kernel broke the build. We need cfb96c7 and e3120f7 to get it building again.

How Has This Been Tested?

Test build only

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Performance enhancement (non-breaking change which improves efficiency)
  • Code cleanup (non-breaking change which makes code smaller or more readable)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Library ABI change (libzfs, libzfs_core, libnvpair, libuutil and libzfsbootenv)
  • Documentation (a change to man pages or other documentation)

43e8f6e introduced a subtle API misuse, in that it passed the output
from vdev_bdev_mode() back into itself. Fortunately, the
SPA_MODE_(READ|WRITE) bit values exactly map to the FMODE_(READ|WRITE) &
BLK_OPEN_(READ|WRITE) bit values, so it didn't result in a bug, but it
was hard to read and understand, so I cleaned it up.

In doing so, I noticed that the only call to vdev_bdev_mode() without
the "exclusive" flag set was in that misuse, and actually, we never do a
non-exclusive blkdev_get_by_path(). So I've just made exclusive be
always-on.

bdev_open_by_path() is replaced by bdev_file_open_by_path(), which
returns a plain old struct file*. Release function is gone entirely; the
regular file release function fput() will take care of the bdev
specifics.

I think this goes without saying, but zfs-2.1.16 will be for Almalinux 8-9 only (not Fedora).

Fix a build error on the github runner:

  Unpacking of 'zfs-2.1.16-1.x86_64.rpm' failed at
  /usr/share/perl5/Alien/Package/Rpm.pm line 168.
