[PATCH v2 02/11] powerpc: Use sysfs_emit() for cpumask show callbacks
From: Yury Norov <hidden>
Date: 2026-07-02 15:47:49
Also in:
driver-core, imx, linux-amlogic, linux-arm-msm, linux-cxl, linux-fpga, linux-pci, linux-perf-users, linux-pm, linux-rdma, lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Linus Torvalds
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().
