Bug Description
SRU Justification
[Impact]
Microsoft has asked for these 3 patches to be applied to the linux-azure-4.15 kernel.
The code has changed significantly from 4.15 to 5.6, so the patches are
quite different then current upstream. Hopefully I've captured the intent
if not the function in those patches.
[1] - Correct corner case where a close operation does not complete.
[2] - Fix a race when an OPEN is cancelled.
[3] - Fix a panic when allocating memory when a spinlock is held.
[Test Case]
none
[Potential regression]
These patches are all intended to accommodate boundary conditions. You shouldn't
experience any regression under normal use.
