From 099619957a0d9ae0e6e5e221493e40fb8fc2cd81 Mon Sep 17 00:00:00 2001 From: Alban Crequy Date: Mon, 7 Dec 2015 01:10:50 +0100 Subject: cgroup2: use new fstype for unified hierarchy Since Linux v4.4-rc1, __DEVEL__sane_behavior does not exist anymore and is replaced by a new fstype "cgroup2". With this patch, systemd no longer supports the old (unstable) way of doing unified hierarchy with __DEVEL__sane_behavior and systemd now requires Linux v4.4 for unified hierarchy. Non-unified hierarchy is still the default and is unchanged by this patch. https://github.com/torvalds/linux/commit/67e9c74b8a873408c27ac9a8e4c1d1c8d72c93ff --- src/basic/cgroup-util.c | 2 +- src/basic/missing.h | 4 ++++ 2 files changed, 5 insertions(+), 1 deletion(-) (limited to 'src/basic') diff --git a/src/basic/cgroup-util.c b/src/basic/cgroup-util.c index 56c1fcaab9..5124b5bf93 100644 --- a/src/basic/cgroup-util.c +++ b/src/basic/cgroup-util.c @@ -2129,7 +2129,7 @@ int cg_unified(void) { if (statfs("/sys/fs/cgroup/", &fs) < 0) return -errno; - if (F_TYPE_EQUAL(fs.f_type, CGROUP_SUPER_MAGIC)) + if (F_TYPE_EQUAL(fs.f_type, CGROUP2_SUPER_MAGIC)) unified_cache = true; else if (F_TYPE_EQUAL(fs.f_type, TMPFS_MAGIC)) unified_cache = false; diff --git a/src/basic/missing.h b/src/basic/missing.h index 034e334e66..66cd5921ad 100644 --- a/src/basic/missing.h +++ b/src/basic/missing.h @@ -437,6 +437,10 @@ struct btrfs_ioctl_quota_ctl_args { #define CGROUP_SUPER_MAGIC 0x27e0eb #endif +#ifndef CGROUP2_SUPER_MAGIC +#define CGROUP2_SUPER_MAGIC 0x63677270 +#endif + #ifndef TMPFS_MAGIC #define TMPFS_MAGIC 0x01021994 #endif -- cgit v1.2.3-54-g00ecf
