| H A D | cpumask.h | 2248ccd80124e61c2c84a22b22409bab452e1f0c Tue Aug 09 12:36:34 CDT 2022 Sander Vanheule <sander@svanheule.net> lib/cpumask: add inline cpumask_next_wrap() for UP
In the uniprocessor case, cpumask_next_wrap() can be simplified, as the
number of valid argument combinations is limited:
- 'start' can only be 0
- 'n' can only be -1 or 0
The only valid CPU that can then be returned, if any, will be the first
one set in the provided 'mask'.
For NR_CPUS == 1, include/linux/cpumask.h now provides an inline
definition of cpumask_next_wrap(), which will conflict with the one
provided by lib/cpumask.c. Make building of lib/cpumask.o again depend
on CONFIG_SMP=y (i.e. NR_CPUS > 1) to avoid the re-definition.
