Subject[PATCH v2 0/4] selftests: add a new test driver for sysfs
Date
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.
