can't fail. Simplify life in rf_BootRaidframe(), and then nuke
rf_lkmgr_mutex_init(). Cleanup rf_threadstuff.h a bit more too.
rf_threadstuff.c is about to Go Away.
Mash DO_RAID_COND in rf_driver.c out of existance.
- Nuke (already #if 0'ed) _rf_create_managed_lkmgr_mutex() while we're
busy here.
simplify DO_INIT in rf_engine.c
here" department.
remove _rf_init_threadgroup() and rf_destroy_threadgroup() which were
already #if 0'ed.
rf_cond_destroy() does nothing. Nuke it, and all callers.
rf_cond_init() doesn't deserve to be a separate function any more.
Fix up the remaining 3 callers, and nuke rf_cond_init().
Another 0.4K goes "poof", but still no functionality lost!
rf_mutex_init(m)
now. The rest of the fluff is no longer needed.
It also cannot fail, so error checking on rf_create_managed_mutex()
is just wasting space.
Nuke the #define's associated with rf_create_managed_mutex().
Convert rf_create_managed_mutex(listp,m) to just rf_mutex_init(m).
Remove wasteful "error checking" and simplify all instances where this
is called. (another 0.3K saved in the binary, but the real savings
is in code readability!)
neither of these ever fail, no need to have a return value. That
makes all the "error detection" on these functions completely
unneeded. But since we're here, if we don't have a return value, then
why not make these macros? My.. look how things keep shrinking, with
no loss in functionality!
the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h,
rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places.
Believe it or not, when this is all done, things will be cleaner.
No functional changes to RAIDframe.
- fire up a new thread for parity re-writes, copybacks, and reconstructs.
The ioctl's which trigger these actions now return immediately.
- add progress accounting for the above actions.
- minor rototillage of rf_netbsdkintf.c to deal with all of the above.
from the tsleep()'s (they probably shouldn't have been there in the
first place!). Making parity re-writing and copybacks interruptable
will require re-designing how a few things are done (e.g. how memory
is freed for structures shipped off to routines that run asynchronously
relative to the calling routine). Fix a few other tsleep's while we're at it.
out-dated comments, and other unneeded stuff. This helps prepare
for cleaning up the rest of the code, and adding new functionality.
No functional changes to the kernel code in this commit.
Carnegie Mellon University. Full RAID implementation, including
levels 0, 1, 4, 5, 6, parity logging, and a few other goodies.
