Subject: [LTP] [PATCH 1/1] kernel/proc01: Whitelist /proc/pressure/*
Date: Mon, 28 Jan 2019 12:14:37 +0100	[thread overview]
Message-ID: <20190128111437.1964-1-pvorel@suse.cz> (raw)

Kernel v4.20 added /proc/pressure/{cpu,io,memory}, when enabled
CONFIG_PSI ("Pressure stall information tracking").
When CONFIG_PSI_DEFAULT_DISABLED is also enabled (and psi=1 kernel
parameter is *not* set) these files are created, but not readable.
