$ git checkout v5.3
HEAD is now at 4d856f72c10ec Linux 5.3
$ git am ~/incoming/_PATCH_v9_5-8_ima_make_process_buffer_measurement__generic.patch
Applying: ima: make process_buffer_measurement() generic
error: patch failed: security/integrity/ima/ima.h:217
error: security/integrity/ima/ima.h: patch does not apply
