[PATCH v2 10/11] perf: Use sysfs_emit() for cpumask show callbacks
From: Yury Norov <hidden>
Date: 2026-07-02 15:48:40
Also in:
driver-core, imx, linux-amlogic, linux-arm-msm, linux-cxl, linux-fpga, linux-pci, linux-perf-users, linux-pm, linux-rdma, linux-rockchip, lkml
Subsystem:
alibaba pmu driver, amlogic ddr pmu driver, applied micro (apm) x-gene soc pmu, arm interconnect pmu drivers, arm pmu profiling and debugging, arm/qualcomm mailing list, compute express link pmu (cpmu), freescale imx ddr pmu driver, marvell pem pmu driver, performance events subsystem, starfive starlink pmu driver, synopsys designware pcie pmu driver, the rest · Maintainers:
Shuai Xue, Jiucheng Xu, Khuong Dinh, Robin Murphy, Will Deacon, Mark Rutland, Jonathan Cameron, Frank Li, Xu Yang, Gowthami Thiagarajan, Geetha sowjanya, Peter Zijlstra, Ingo Molnar, Arnaldo Carvalho de Melo, Namhyung Kim, Ji Sheng Teoh, Jing Zhang, 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().
