Subject: perf lock: Fix option value type in parse_max_stack
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cfaade34b52aa1ec553044255702c4b31b57c005;p=thirdparty%2Fkernel%2Fstable.git

perf lock: Fix option value type in parse_max_stack

The value is a void* and the address of an int, max_stack_depth, is
set up in the perf lock options. The parse_max_stack function treats
the int* as a long*, make this more correct by declaring the value to
be an int*.
