File uapi-linux-prctl-provide-macro-definitions-for-the-PR_SCHED_CORE-type-argument of Package linux-glibc-devel
From: Eugene Syromiatnikov <esyr@redhat.com> Date: Wed, 25 Aug 2021 19:06:13 +0200 Subject: uapi/linux/prctl: provide macro definitions for the PR_SCHED_CORE type argument Git-commit: 61bc346ce64a3864ac55f5d18bdc1572cda4fb18 Patch-mainline: v5.16-rc1 References: bsc#1194659 Commit 7ac592aa35a684ff ("sched: prctl() core-scheduling interface") made use of enum pid_type in prctl's arg4; this type and the associated enumeration definitions are not exposed to userspace. Christian has suggested to provide additional macro definitions that convey the meaning of the type argument more in alignment with its actual usage, and this patch does exactly that.
