proccess are forked with this limit and only then they restore their
limits, but

The idea is to use mutex for protecting callback execution agains per-net
callback shutdown and destroying all the net-related backchannel requests
before transports destruction.

sunrpc: bc_svc_flush_queue_net() helper introduced
nfs: protect callback
From: Stanislav Kinsburskiy
Here is the race:
CPU #0 CPU#1
cleanup_mnt nfs41_callback_svc (get xprt from the list)
nfs_callback_down ...
... ...
svc_close_net ...
From: Stanislav Kinsburskiy
This helper can be used to remove backchannel requests from callback queue on
per-net basis.

When split_huge_page_to_list() fails, and a huge page is going back
to LRU, the number of isolated pages is decreasing. So we must
subtract HPAGE_PMD_NR from NR_ISOLATED_ANON counter, not to add it.
Otherwise, we may bumped into a situation, when number of isolated
pages grows up to number of
