Whitespace damage?

pinned by kfd and add it back to kfd availability to
remove the double accounting.

Our assumptions about how much KFD memory is currently available for
allocation may be violated by various complexities so we define the
reported value as advisory, however we should never report negative
availability.

Will do.

Patch 1 adds kfd_lock_pdd_by_id and patch 2 adds kfd_unlock_pdd helpers,
broken out this way to reduce noise in the first patch, which is a bit
tricky because of modifying a lot of error paths. Patch 2 is trivial.

Trivially changes kfd_lock_pdd_by_id ... mutex_unlock to use the
kfd_unlock_pdd helper.

Seperately accumulate a statistic of rounded up allocations to use
to report availability, with a view to increasing the likelihood a
buffer object can be successfully allocated at exactly the size
reported by the availability API.

Rounding up allocations in the allocation path caused test regressions,
so now just round in the availability path.

Hi all,
This patch adds thunk support for the new KFD memory availability ioctl.
I am posting this patch inline with Thunderbird just for now, to establish
the principle that I can post patches/code old school style without
mangling whitespace. Please bear with me while I get that sorted out. I
