Enji Cooper	193d9e768b	sys/modules: normalize .CURDIR-relative paths to SRCTOP ... This simplifies make output/logic Tested with: `cd sys/modules; make ALL_MODULES=` on amd64 MFC after: 1 month Sponsored by: Dell EMC Isilon	2017-03-04 10:10:17 +00:00
Pawel Jakub Dawidek	565bc10111	Add a very simple and small GEOM class - ZERO. ... It creates very huge provider (41PB) /dev/gzero. On BIO_READ request it zero-fills bio_data and on BIO_WRITE it does nothing. You can also set kern.geom.zero.clear sysctl to 0 to do nothing even for BIO_READ. I'm using it for performance testing where it is very helpful. MFC after: 3 days	2005-07-25 10:03:16 +00:00
