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 ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
