Subject: special case when exiting FS - don't core dump and don't tell FS about it
X-Git-Tag: v3.1.2a~257
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/index.html?a=commitdiff_plain;h=9b1d4ef23324e976b8b94262c89089d94d2beb01;p=minix.git

special case when exiting FS - don't core dump and don't tell FS about it
Because if FS is hanging in a signal, the exit won't work.
This way FS gets exited on e.g. SIGSEGV.
