Remove all traces of Julians DEVFS (incl from kern/subr_diskslice.c)

2000-08-20T21:34:39Z

Remove old DEVFS support fields from dev_t. Make uid, gid & mode members of dev_t and set them in make_dev(). Use correct uid, gid & mode in make_dev in disk minilayer. Add support for registering alias names for a dev_t using the new function make_dev_alias(). These will show up as symlinks in DEVFS. Use makedev() rather than make_dev() for MFSs magic devices to prevent DEVFS from noticing this abuse. Add a field for DEVFS inode number in dev_t. Add new DEVFS in fs/devfs. Add devfs cloning to: disk minilayer (ie: ad(4), sd(4), cd(4) etc etc) md(4), tun(4), bpf(4), fd(4) If DEVFS add -d flag to /sbin/inits args to make it mount devfs. Add commented out DEVFS to GENERIC

Introduce vop_stdinactive() and make it the default if no vop_inactive

Virtualizes & untangles the bioops operations vector.

. is now a prerequisite for but it shall not be made a nested include according to bdes teachings on the subject of nested includes. Diskdrivers and similar stuff below specfs::strategy() should no longer need to include unless they need caching of data. Still a few bogus uses of struct buf to track down. Repocopy by: peter

Complete the bio/buf divorce for all code below devfs::strategy

2000-04-15T05:54:02Z

Exceptions: Vinum untouched. This means that it cannot be compiled. Greg Lehey is on the case. CCD not converted yet, casts to struct buf (still safe) atapi-cd casts to struct buf to examine B_PHYS

Move B_ERROR flag to b_ioflags and call it BIO_ERROR.

2000-04-02T15:24:56Z

(Much of this done by script) Move B_ORDERED flag to b_ioflags and call it BIO_ORDERED. Move b_pblkno and b_iodone_chain to struct bio while we transition, they will be obsoleted once bio structs chain/stack. Add bio_queue field for struct bio aware disksort. Address a lot of stylistic issues brought up by bde.

Rename the existing BUF_STRATEGY() to DEV_STRATEGY()

substitute BUF_WRITE(foo) for VOP_BWRITE(foo->b_vp, foo) substitute BUF_STRATEGY(foo) for VOP_STRATEGY(foo->b_vp, foo) This patch is machine generated except for the ccd.c and buf.h parts.

Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new

field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!) Vinum users: Greg has not had time to test this yet, be careful.

Eliminate the undocumented, experimental, non-delivering and highly
