kris 2005-10-14 19:15:10 UTC FreeBSD src repository Modified files: sys/kern subr_param.c Log: Partially revert revision 1.66, which contained a change that did not correspond to the commit log. It changed the maxswzone and maxbcache parameters from int to long, without changing the extern definitions in <sys/buf.h>. In fact it's a good thing it did not, because other parts of the system are not yet ready for this, and on large-memory sparc machines it causes severe filesystem damage if you try. The worst effect of the change was that the tunables controlling the above variables stopped working. These were necessary to allow such large sparc64 machines (with >12GB RAM) to boot, since sparc64 did not set a hard-coded upper limit on these parameters and they ended up overflowing an int, causing an infinite loop at boot in bufinit().
