* format_config: Replace long format lines.Greg Lehey2001-05-221-18/+28
| | | | | | | | | | | | | | | | | Requested by: bde Add retryerrors keyword. vinum_scandisk: Print a different message if an inadvertent start command did not find any additional drives. The previous message "no drives found" confused and worried many people. MFS: vinum_open: Recognize Mylex devices as storage devices. Notes: svn path=/head/; revision=76958

| | | | | | | | | | | | | | | In case of error, check the VF_RETRYERRORS flag in the subdisk and don't take the subdisk down if it's set, just retry the I/O. Requested by: peter If the buffer has been copied (XFR_COPYBUF), release the copied buffer when the I/O completes. Suggested by: alfred Notes: svn path=/head/; revision=76957

* Fix vinum for both devfs and non-devfs systems.Alfred Perlstein2001-02-202-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | userland tool: Use the vfs.devfs.generation sysctl to test for devfs presense (thanks phk!) when devfs is active it will not try to create the device nodes in /dev and therefore will not complain about the failure to do so. Revert the change in the #define for VINUM_DIR in the kernel header so that vinum can find its device nodes. Replace perror() with vinum_perror() to print file/line when DEVBUG is defined (not defined by default). kernel: Don't use the #define names for the "superdev" creation since they will be prepended by "/dev/" (based on VINUM_DIR), instead use string constants. Create both debug and non-debug "superdev" nodes in the devfs. Problem noticed and fix tested by: Martin Blapp <mblapp@fuchur.lan.attic.ch> Notes: svn path=/head/; revision=72777
* forced commit to note that the last delta also reordered some code inAlfred Perlstein2001-02-201-1/+1
| | | | | | | | | | | | | | remove_sd_entry() to: Simplify (hopefully) it by moving all error returns closer to the beginning of the function. Return an error when "Error removing subdisk %s: not found in plex %s\n" would have been reported, as I doubt that we are "OK" after printing that error message. Notes: svn path=/head/; revision=72769
* Take a shot at making vinum devfs aware.Alfred Perlstein2001-02-204-19/+57
| | | | | | | | | | | | | | | | | | | | Adding make_dev() and destroy_dev() calls in (hopefully) the right places. This is done by calling make_dev() in each object constructor and caching the dev_t's returned from make_dev() in each struct 'subdisk'(sd), 'plex' and 'volume' such that the 'object'_free() functioncs can call destroy dev. This change makes a subset of the old /dev/vinum appear under devfs. Enough nodes appear such that I'm able to mount my striped volume. There may be more work needed to get vinum configuration working properly. Notes: svn path=/head/; revision=72766
* Change and clean the mutex lock interface.Bosko Milekic2001-02-092-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mtx_enter(lock, type) becomes: mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks) mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized) similarily, for releasing a lock, we now have: mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN. We change the caller interface for the two different types of locks because the semantics are entirely different for each case, and this makes it explicitly clear and, at the same time, it rids us of the extra `type' argument. The enter->lock and exit->unlock change has been made with the idea that we're "locking data" and not "entering locked code" in mind. Further, remove all additional "flags" previously passed to the lock acquire/release routines with the exception of two: MTX_QUIET and MTX_NOSWITCH The functionality of these flags is preserved and they can be passed to the lock/unlock routines by calling the corresponding wrappers: mtx_{lock, unlock}_flags(lock, flag(s)) and mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN locks, respectively. Re-inline some lock acq/rel code; in the sleep lock case, we only inline the _obtain_lock()s in order to ensure that the inlined code fits into a cache line. In the spin lock case, we inline recursion and actually only perform a function call if we need to spin. This change has been made with the idea that we generally tend to avoid spin locks and that also the spin locks that we do have and are heavily used (i.e. sched_lock) do recurse, and therefore in an effort to reduce function call overhead for some architectures (such as alpha), we inline recursion for this case. Create a new malloc type for the witness code and retire from using the M_DEV type. The new type is called M_WITNESS and is only declared if WITNESS is enabled. Begin cleaning up some machdep/mutex.h code - specifically updated the "optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently need those. Finally, caught up to the interface changes in all sys code. Contributors: jake, jhb, jasone (in no particular order) Notes: svn path=/head/; revision=72200

* struct rangelock: Remove the field 'plex' from the entry. Range locksGreg Lehey2001-01-142-7/+3

* Remove obsolete functions [un]lockplex and [un]lockvol.Greg Lehey2001-01-101-139/+64
| | | | | | | | | | | | | | | | Rewrite lockrange and unlockrange. The lock table is now a fixed size, so there is no possibility for race conditions when expanding. The current size (256 locked ranges) should be large enough that it makes no sense to expand it. To do expansion right would require quiescing the plex (requiring at least 256 I/O completions), and the performance implications are horrendous. Add a mutex per plex for accessing the lock table.
