Hi,
This one must NOT be included. It generates a regression.
This should be removed from 5.4 as well.
See 13f2d25b951f139064ec2dd53c0c7ebdf8d8007e.
There is also a thread on ML about it. I couldn't find it right away,
but I'm sure that Dan will be quicker than me for finding it, if needed

As of commit 8c0637e950d6 ("keys: Make the KEY_NEED_* perms an enum rather

wants to do with the key. Add KEY_NEED_SEARCH to fix a warning with the

It's actually not a surprise, it's a known limitation/exception.
Partially it was so because historically there was no way to account
percpu memory, and some bpf maps can are using it quite extensively.
Fortunately, it changed recently, and 5.9 will likely get an ability
to account

Since commit 726721a51838 ("tracing: Move synthetic events to

boot-time tracing also has to check CONFIG_SYNTH_EVENT instead

Fix the event trigger to accept redundant spaces in

When I increased the upper bound of the min_free_kbytes value in
ee8eb9a5fe863, I forgot to tweak the above comment to reflect
the new value. This patch fixes that mistake.
In addition, this patch replaces the magic number bounds with symbolic
constants to clarify the logic.

You need to learn how this driver's locking works and design a correct
adjustment.
