Merge branch 'Sleepable local storage'
KP Singh says:
====================
Local storage is currently unusable in sleepable helpers. One of the
important use cases of local_storage is to attach security (or
performance) contextual information to kernel objects in LSM / tracing
programs to be used later in the life-cyle of the object.
Sometimes this context can only be gathered from sleepable programs
(because it needs accesing __user pointers or helpers like
bpf_ima_inode_hash). Allowing local storage to be used from sleepable
programs allows such context to be managed with the benefits of
local_storage.
# v2 -> v3
* Fixed some RCU issues pointed by Martin
* Added Martin's ack
# v1 -> v2
* Generalize RCU checks (will send a separate patch for updating
non local storage code where this can be used).
* Add missing RCU lock checks from v1
