I think it would be nicer to initialize at the top of the function as

Hi Peter,
Thank you as always for taking a look. This change relies on the
existing check in vma_to_resize on line 686:

Yes, the mremap(2) man page was updated when this flag was added and
it will require a further update to reflect this expanded mapping

Currently MREMAP_DONTUNMAP only accepts private anonymous mappings. This change
will widen the support to include shmem mappings. The primary use case
is to support MREMAP_DONTUNMAP on mappings which may have been created from
a memfd.

ibmvfc_init_sub_crqs can sleep, for multiple reasons, so you can't hold
a lock when you call it. There is a GFP_KERNEL allocation in it, and the
patch before this one adds an msleep in an error path.

Ah, good catch. So this may not be a true overflow issue at all, even
if it's confusing and bad code. The "problem" is that this piece of
the struct is variable-length, and unless we're going to dynamically
resize/reallocate the whole buffer, we have to assume the initial
allocation was large enough (and per your note, it is).

You can also remove screen_bitmap from struct vm86 (the kernel
internal structure), and the check_v8086_mode() function.

nd I don't have specific
examples off the top of my head, but perhaps based on the ability of
various structures to change formats and the ability of log vectors to
shrink in size, shouldn't we expect the possibility of a CIL context to
shrink in size as well? Just from poking around the CIL it seems like
the surrounding code supports it (xlog_cil_insert_items() checks len > 0
for recalculating split res as well)...

Ah, you're right. This individual patch looks good to me.

I don't think this situation can ever happen MREMAP_DONTUNMAP is
already restricted to anonymous mappings (defined as not having
vm_ops) and vma_to_resize checks that the mapping is anonymous before
move_vma is called.

I'd also note that we don't operate in AP mode -- only STA -- and IIRC
Ben, you've complained about AP mode in the past.

It might be useful to dump the values under /sys/fs/xfs//log/* for
each fs to get an idea of the state of the logs as well...
