Re: [PATCH 13/16] perf: Use sysfs_emit() for cpumask show callbacks

Fri, 29 May 2026 04:07:34 -0700

These callbacks are sysfs show paths.

Use sysfs_emit() and cpumask_pr_args() to emit the masks.

This prepares for removing cpumap_print_to_pagebuf().
TBH, looking at this diff I think it only shows the value of having a helper to abstract the boilerplate...
I'm not sure I agree with the argument of removing something entirely just because it may occasionally be misused, but could we at least have something like: 

#define sysfs_emit_cpumask(buf, mask) \
        sysfs_emit((buf), "%*pbl\n", cpumask_pr_args(mask))
to save the mess in all the many places where the current cpumap_print_to_pagebuf() usage _is_ entirely appropriate? 

Thansk,
Robin.
