memory. Since we only now ever "return(0)", just return (void)
instead.
Cleanup all uses of rf_ShutdownCreate() to not worry about
it ever failing. Shaves another 600 bytes off of an i386 GENERIC kernel.
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!)
- all freelists converted to pools
- initialization of structure members in certain cases where
code was relying on specific allocation and usage properties
to keep structures in a "known state" (that doesn't work with
pools!).
- make most pool_get() be "PR_WAITOK" until they can be analyzed
further, and/or have proper error handling added.
- all RF_Mallocs zero the space returned, so there is no difference
between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s
do is tend to do is get things horribly confused.
Make RF_Malloc() the "general memory allocator", with
RF_MallocAndAdd() the "general memory allocator with
allocation list".
- some of these RF_Malloc's et al. are destined to disappear.
- remove rf_rdp_freelist entirely (it's not used anywhere!)
- remove: #include "rf_freelist.h"
- to the files that were relying on the above, add: #include "rf_general.h"
- add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy
about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now
weighs in at about 162K on i386.
of strenuous agreement, and some general agreement, this commit is
going ahead because it's now starting to block some other changes I
wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe.
While the "row" interface has been exported to the world, RAIDframe
internals have really only supported a single row, even though they
have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to
specify a single row, etc. All auto-config structures remain fully
forward/backwards compatible.
The only visible difference to the average user should be a
reduction in the size of a GENERIC kernel (i386) by 4.5K. For those
of us trolling through RAIDframe kernel code, a lot of the driver
configuration code has become a LOT easier to read.
sort of error message, over and over again, in different files.
Rather than having the same text repeated in multiple .o files,
create a couple of little functions to do the printing, and save a
bundle of space. Also improves readability of code.
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.
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.
