There's currently a lot of momentum behind io_uring which could not only
enable efficient enumeration and retrieval of small files but maybe it
would also be a more natural place for an API like task_diag..

so lots of read syscalls are still required. However I may not

Regardless, text-based formats can't match the efficiency of task_diag,
but binary ones are also possible.

Second follow-up patch updates (the sole) usage site of this constant
in kernel to use the new spelling.
The old name is retained as it is part of UAPI now.

This patch introduces two configuration options,
BPF_JIT_HARDEN_BOOTPARAM and BPF_JIT_HARDEN_BOOTPARAM_VALUE, that allow
configuring the initial value of net.core.bpf_jit_harden sysctl knob,
which is useful for enforcing JIT hardening during the early boot.

Hello.
This patch set adds ability to set default values for
kernel.unprivileged_bpf_disable, net.core.bpf_jit_harden,
net.core.bpf_jit_kallsyms sysctl knobs as well as option to override
them via a boot-time kernel parameter.

Looks like this change changed the size of struct hfi1_ctxt_info and the
value of HFI1_IOCTL_CTXT_INFO ioctl number as a result.

For some reason, the implementation of these two 16-bit ID system calls
used cast instead of low2highgid/low2highuid macros for converting [GU]IDs,
which leads to incorrect handling of value of -1 (which ought to be
considered invalid).
