It is very straight forward and can limit the abosolute numbers of common rdma constructs used by different cgroups. - kernel/cgroup.c got too chubby and disorganized. Created kernel/cgroup/ subdirectory and moved all cgroup related files under kernel/ there and reorganized the core code. This hurts for backporting patches but was long overdue. - cgroup v2 process listing reimplemented so that it no longer depends on allocating a buffer large enough to cache the entire result to sort and uniq the output. v2 has always mangled the sort order to ensure that users don't depend on the sorted output, so this shouldn't surprise anybody. This makes the pid listing functions use the same iterators that are used internally, which have to have the same iterating capabilities anyway. - perf cgroup filtering now works automatically on cgroup v2. This patch was posted a long time ago but somehow fell through the cracks. - misc fixes asnd documentation updates" * 'for-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: (27 commits) kernfs: fix locking around kernfs_ops->release() callback cgroup: drop the matching uid requirement on migration for cgroup v2 cgroup, perf_event: make perf_event controller work on cgroup2 hierarchy cgroup: misc cleanups cgroup: call subsys->*attach() only for subsystems which are actually affected by migration cgroup: track migration context in cgroup_mgctx cgroup: cosmetic update to cgroup_taskset_add() rdmacg: Fixed uninitialized current resource usage cgroup: Add missing cgroup-v2 PID controller documentation. rdmacg: Added documentation for rdmacg IB/core: added support to use rdma cgroup controller rdmacg: Added rdma cgroup controller cgroup: fix a comment typo cgroup: fix RCU related sparse warnings cgroup: move namespace code to kernel/cgroup/namespace.c cgroup: rename functions for consistency cgroup: move v1 mount functions to kernel/cgroup/cgroup-v1.c cgroup: separate out cgroup1_kf_syscall_ops cgroup: refactor mount path and clearly distinguish v1 and v2 paths cgroup: move cgroup v1 specific code to kernel/cgroup/cgroup-v1.c ...
| * IB/core: added support to use rdma cgroup controllerParav Pandit2017-01-101-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | Added support APIs for IB core to register/unregister every IB/RDMA device with rdma cgroup for tracking rdma resources. IB core registers with rdma cgroup controller. Added support APIs for uverbs layer to make use of rdma controller. Added uverbs layer to perform resource charge/uncharge functionality. Added support during query_device uverb operation to ensure it returns resource limits by honoring rdma cgroup configured limits.

This process requires that 1 bit fields are declared as u8 in the unpacked struct, otherwise the packing process does not read the value properly and the packed result is wired to 0. Several places wrongly used int. Crucially this means the kernel has never, set reversible correctly in the path record request. It has always asked for irreversible paths even if the ULP requests otherwise. When the kernel is used with a SM that supports this feature, it completely breaks communication management if reversible paths are not properly requested. The only reason this ever worked is because opensm ignores the reversible bit.
