Extend the slub_debug syntax to "slub_debug=<flags>[,<slub>]*", where <slub> may contain an asterisk at the end. For example, the following would poison all kmalloc slabs: slub_debug=P,kmalloc* and the following would apply the default flags to all kmalloc and all block IO slabs: slub_debug=,bio*,kmalloc* Please note that a similar patch was posted by Iliyan Malchev some time ago but was never merged: https://marc.info/?l=linux-mm&m=131283905330474&w=2 Link: http://lkml.kernel.org/r/20180928111139.27962-1-atomlin@redhat.com Signed-off-by: Aaron Tomlin <atomlin@redhat.com> Acked-by: Christoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: Iliyan Malchev <malchev@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
