Subject: Are CAP_SYS_ADMIN and CAP_SYS_NICE still needed for SQPOLL?
Date: Thu, 25 Mar 2021 12:33:22 +0100 [thread overview]
Message-ID: <20210325113322.ecnji3xejozqdpwt@steredhat> (raw)
Hi Jens, Hi Pavel,
I was taking a look at the new SQPOLL handling with io_thread instead of
kthread. Great job! Really nice feature that maybe can be reused also in
other scenarios (e.g. vhost).
Regarding SQPOLL, IIUC these new threads are much closer to user
threads, so is there still a need to require CAP_SYS_ADMIN and
CAP_SYS_NICE to enable SQPOLL?
Thanks,
Stefano
