X-Git-Tag: v6.13-rc1~206^2~72
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f2e9d46ac62ff2b01ae168f88739ae99ff376f2e;p=thirdparty%2Fkernel%2Flinux.git

s390/cpum_sf: Use sf_buffer_available()

Use sf_buffer_available() consistently throughtout the code
to test for the existence of sampling buffer.
No functional change.
