Hi,

I'm chasing intermittent memory corruption bugs seen at least on rc5,
rc6, and yesterday's HEAD (98b9f8a4549909c6), on arm64. 

It looks like we make use of dangling references to a freed struct file,
which is caught by KASAN. Without KASAN, I see a number of other
intermittent issues that I suspect are the result of this memory
corruption. I've included an example splat below, complete with KASAN's
alloc/free traces at the end of this mail.

Is it possible this is the same issue as the one fixed by
