Subject: Don't repeat out-of-space messages
X-Git-Tag: v3.2.0~165
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/Bv9ARM.html?a=commitdiff_plain;h=c89bc850091b8dede71c81e19d681e4aefbbbf4e;p=minix.git

Don't repeat out-of-space messages

This patch makes PFS, EXT2 and MFS print only once that they're out of
space. After freeing up space and running out of space again, the message
will be printed again also.
