Description
In the Linux kernel, the following vulnerability has been resolved:
afs: Fix netns teardown to cancel the preallocation charger
Fix the teardown of an afs network namespace to make sure it cancels the
work item that keeps the preallocated rxrpc call/conn/peer queue charged
before incoming calls are disabled (i.e. listen 0).
Also, if net->live is false because the afs netns is being deleted, make
afs_charge_preallocation() skip charging and make afs_rx_new_call() avoid
requeuing the charger.
(This was found by AI review).
