Subject: tools/mm/slabinfo: Fix trace disable logic inversion
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=235ab68d67eadbef1fdbfb771f21f5bacc77a2ae;p=thirdparty%2Fkernel%2Flinux.git

tools/mm/slabinfo: Fix trace disable logic inversion

The disable trace path in slab_debug() had a logic error where it would
set trace=1 instead of trace=0. This made trace functionality permanently
enabled once turned on for any slab cache.
