phk 1999/10/09 12:44:33 PDT Modified files: sys/sys buf.h sys/kern kern_physio.c Log: Give physio a makeover. - Let physio take read/write compatible args and have it use uio->uio_rw to determine the direction. - physread/physwrite are now #defines for physio - Remove the inversly named minphys(), dev->si_iosize_max takes over. - Physio() always uses pbufs. - Fix the check for non page-aligned transfers, now only unaligned transfers larger than (MAXPHYS - PAGE_SIZE) get fragmented (only interesting for tapes using max blocksize). - General wash-and-clean of code.
