Poul-Henning Kamp aa4f4b695e Move the buffered read/write code out of spec_{read|write} and into ... two new functions spec_buf{read|write}. Add sysctl vfs.bdev_buffered which defaults to 1 == true. This sysctl can be used to experimentally turn buffered behaviour for bdevs off. I should not be changed while any blockdevices are open. Remove the misplaced sysctl vfs.enable_userblk_io. No other changes in behaviour.		1999-10-04 11:23:10 +00:00
