Subject: [GIT PULL] XArray for 5.5
Date: Wed, 22 Jan 2020 22:41:40 -0800	[thread overview]
Message-ID: <20200123064140.GG4675@bombadil.infradead.org> (raw)


I had an oops live on stage at linux.conf.au this year, and it turned out
to be a bug in xas_find() which I can't prove isn't triggerable in the
current codebase.  Then in looking for the bug, I spotted two more bugs.
The bots have had a few days to chew on this with no problems reported,
and it passes the test-suite (which now has more tests to make sure
these problems don't come back).

So I feel pretty comfortable asking you to pull this, even though it's
so late in the development cycle.

The following changes since commit 0058b0a506e40d9a2c62015fe92eb64a44d78cd9:
