[PATCH] block: avoid null pointer dereference on null disk

From: Colin Ian King It is possible that the pointer disk can be null and hence we can get a null pointer deference when accessing disk->flags. Add a null pointer check to avoid the dereference. Detected by CoverityScan, CID#1461133 ("Explicit null dereferenced")

On AMD platforms, under certain conditions insn_len may be zero on #NPF. This can happen if a guest gets a page-fault on data access but the HW table walker is not able to read the instruction page (e.g instruction page is not present in memory). Typically, when insn_len is zero,

[PATCH v2 2/2] cgroup: export list of cgroups v2 features using sysfs

The active development of cgroups v2 sometimes leads to a creation of interfaces, which are not turned on by default (to provide backward compatibility). It's handy to know from userspace, which cgroup v2 features are supported without calculating it based on the kernel version. So, let's export

[PATCH v2 1/2] cgroup: export list of delegatable control files using sysfs

Delegatable cgroup v2 control files may require special handling (e.g. chowning), and the exact list of such files varies between kernel versions (and likely to be extended in the future). To guarantee correctness of this list and simplify the life of userspace (systemd, first of all), let's
