Subject: [RELEASE] Userspace RCU 0.15.1

Hi,

I've released Userspace RCU v0.15.1. The main purpose is fixing a
missing include of stdlib.h in a public header. It's a small bug, but it
caused enough issues for end users to justify a release.

liburcu is a LGPLv2.1 userspace RCU (read-copy-update) library. This
data synchronization library provides read-side access which scales
linearly with the number of cores. It does so by allowing multiple
copies of a given data structure to live at the same time, and by
monitoring the data structure accesses to detect grace periods after
which memory reclamation is possible.

liburcu-cds provides efficient data structures based on RCU and
lock-free algorithms. Those structures include hash tables, queues,
stacks, and doubly-linked lists.

Changelog:

2025-02-18 [*] Userspace RCU 0.15.1
         * uatomic/generic: Add missing #include <stdlib.h>
         * docs: Clarify that make is required to build the project
         * fix: add missing SPDX headers to urcu/uatomic/api.h
         * compiler.h: Remove caa_unqual_scalar_typeof

Project website: https://liburcu.org
Git repository: git://git.liburcu.org/urcu.git

[*] note the Changelog file in the liburcu v0.15.1 release has
     2025-01-18 which is incorrect. I unfortunately noticed it too late
     for the release, but it's fixed in the stable-0.15 branch for
     the next release.

Thanks,

Mathieu
