Andriy Gapon eacdf85d44 dtrace: add a knob to control maximum size of principal buffers ... We had a hardcoded limit of 1/128-th of physical memory that was further subdivided between all CPUs as principal buffers are allocated on the per-CPU basis. Actually, the buffers could use up 1/64-th of the memmory because with the default switch policy there are two buffers per CPU. This commit allows to change that limit. Note that the discussed limit is per dtrace command invocation. The idea is to limit the size of a single malloc(9) call, not the total memory size used by DTrace buffers.
