Subject: [PATCH v2 0/4] selftests: add a new test driver for sysfs
Date: Fri,  2 Jul 2021 17:46:28 -0700	[thread overview]
Message-ID: <20210703004632.621662-1-mcgrof@kernel.org> (raw)

This v2 rebases onto the latest linux-next tag, next-20210701. A few
changes were needed, namely:

  1) changes kernfs_init_failure_injection() to return int instead
     of void. On the latest linux-next we have a new static build
     check for this, so this mistake was captured when building.

  2) I made kernfs_init_failure_injection static

  3) lib/test_sysfs.c moved to the new blk_alloc_disk() added by
     Christoph as direct queue allocation is no longer supported,
     ie, blk_alloc_queue() is no longer exported. This work was
     done by Christoph in preparation to help make add_disk*()
     callers eventually return an error code and make the error
     handling much saner. Because of this same change
     blk_cleanup_queue() is no longer needed so we embrace
     the shiny new blk_cleanup_disk().

I've put this up on my linux-next git tree [0] under the branch
named 20210701-sysfs-fix-races-v2.
