From: Li RongQing Date: Tue, 31 Mar 2026 05:32:45 +0000 (-0400) Subject: scsi: qla2xxx: Use nr_cpu_ids instead of NR_CPUS for qp_cpu_map allocation X-Git-Url: http://git.ipfire.org/index.cgi?a=commitdiff_plain;h=271aeff266c9ca97eae315d59ef0bfe0e4ce0a94;p=thirdparty%2Fkernel%2Flinux.git scsi: qla2xxx: Use nr_cpu_ids instead of NR_CPUS for qp_cpu_map allocation Change the memory allocation for qp_cpu_map to use the actual number of CPUs ('nr_cpu_ids') instead of the maximum possible CPUs ('NR_CPUS'). This saves memory on systems where the maximum CPU limit is much higher than the active CPU count.
