Subject: iscsi-target: move iscsit_thread_check_cpumask()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c0b7373be811307c5ff1de8c8547aae3597d24aa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iscsi-target: move iscsit_thread_check_cpumask()

Move iscsit_thread_check_cpumask() to header
file so that ISCSI_HW_OFFLOAD and other transport drivers
can call this function to ensure both tx and rx thread
runs on same cpu.
