sock: annotate data-races around prot->memory_pressure

Browse source

[ Upstream commit 76f33296d2 ]

*prot->memory_pressure is read/writen locklessly, we need
to add proper annotations.

A recent commit added a new race, it is time to audit all accesses.

Fixes: 2d0c88e84e ("sock: Fix misuse of sk_under_memory_pressure()")
Fixes: 4d93df0abd ("[SCTP]: Rewrite of sctp buffer management code")
