dynamic_debug: dynamic hex dump
Introduce print_hex_dump_debug() that can be dynamically controlled, similar to pr_debug. Also, make print_hex_dump_bytes() dynamically controlled Implement only 'p' flag (_DPRINTK_FLAGS_PRINT) to keep it simple since hex dump prints multiple lines and long prefix would impact readability. To provide line/file etc. information, use pr_debug or similar before/after print_hex_dump_debug() Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: Jason Baron <jbaron@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
