Subject: [Intel-wired-lan] [PATCH net 0/2] ice: avoid sleeping/scheduling in atomic contexts
Date: Wed, 23 Mar 2022 13:43:51 +0100	[thread overview]
Message-ID: <20220323124353.2762181-1-alexandr.lobakin@intel.com> (raw)

The `ice_misc_intr() + ice_send_event_to_aux()` infamous pair failed
once again.
Fix yet another (hopefully last one) 'scheduling while atomic' splat
and finally plug the hole to gracefully return prematurely when
invoked in wrong context instead of panicking.

Alexander Lobakin (2):
  ice: fix 'scheduling while atomic' on aux critical err interrupt
  ice: don't allow to run ice_send_event_to_aux() in atomic ctx

Urgent fix, would like to make it directly through -net.
