2013-07-19	Don't use uninitialized variable when a simple 0 will do.	Kenneth R Westerback
	Found by Maxime Villard. ok jsing@
2013-07-01	When an I/O error occurs on a softraid chunk, only take it offline if the	Joel Sing
	discipline supports redundancy. In the non-redundant case, there is little to gain my failing the chunk, in fact it just makes any form of data recovery significantly harder. ok krw@ todd@
2013-06-11	final removal of daddr64_t. daddr_t has been 64 bit for a long enough	Theo de Raadt
	test period; i think 3 years ago the last bugs fell out. ok otto beck others
2013-05-21	Ensure that sc_lock is held when calling sr_meta_native_bootprobe() - the	Joel Sing
	softraid status functions will complain otherwise. Found the hard way by ajacoutot@
2013-05-21	sr_raid_startwu() is no longer called from interrupt context, hence does	Joel Sing
	not need to invoke a workq-based callback.
2013-05-21	Provide a function that handles the scheduling of work units. This	Joel Sing
	simplifies the discipline code, avoids code duplication and moves the scheduling logic into a single location. ok krw@
2013-05-21	Make the sr_raid_startwu() function handle deferred work units, instead of	Joel Sing
	the caller having to handle the state changes.
2013-05-21	Fix missing work unit state initialisations.	Joel Sing

2013-05-21	Use a state to indicate that a work unit should only be constructed and not	Joel Sing
	scheduled, rather than trying to imply this from the rebuild flag.
2013-04-26	Add a SR_WUF_DISCIPLINE flag that identifies work units that have resulted	Joel Sing
	from discipline specific I/O. Such work units are not associated with a SCSI xfer and are returned via sr_wu_put() on completion.
2013-04-23	Rename ccb_flag to ccb_flags.	Joel Sing

2013-04-21	Convert RAID1 to the new work unit completion functions and generic	Joel Sing
	interrupt handler. Disciplines such as RAID1/4/5/6 need a way to intercept I/O when the work unit is complete, but before the SCSI xfer is complete. This is provided via a sd_scsi_wu_done hook, which enables work units to be restarted or otherwise modified before the SCSI xfer completion occurs. ok krw@
2013-03-31	Use the discipline name instead of the product string when reporting the	Joel Sing
	attachment.
2013-03-31	The return value of sd_free_resources() is never checked and all of the	Joel Sing
	implementations only ever returned zero. Change the return value from int to void instead of pretending it might mean something.
2013-03-31	Fix compilation with debug.	Joel Sing

2013-03-31	Provide default resource allocation and free functions. Convert all	Joel Sing
	disciplines except for AOE and CRYPTO, which require custom handlers.
2013-03-30	Provide wrappers for scsi_io_get() and scsi_io_put(), that also include	Joel Sing
	the sd_sync check/wakeup. Remove some unnecessary NULL checks whilst here. ok krw@
2013-03-30	Provide a default discipline interrupt handling function and migrate all of	Joel Sing
	the disciplines that now have the same interrupt code. ok krw@
2013-03-29	Decouple wakeups on work unit completion from the type of I/O being	Joel Sing
	performed. ok krw@
2013-03-29	sd_wu_pending is only decremented when scsi_done() or scsi_io_put() are	Joel Sing
	called. As a result, factor out the the sd_sync check/wakeup code and move it to after the scsi_done() call in sr_scsi_done(). Perform the same sd_sync check/wakeup after scsi_io_put() calls (including the addition of some that were previously missed). ok krw@
2013-03-25	Factor out the code that is used to recreate work units - one copy of the	Joel Sing
	code is sufficient. ok krw@
2013-03-10	Rename sc_dis to sc_targets, since it is an array of targets that also	Joel Sing
	happen to be softraid disciplines. ok krw@
2013-03-05	Track attached softraid disciplines via a queue. This prevents the need to	Joel Sing
	scan the sparse SCSI targets array and simplifies code. Disciplines are now also shutdown in reverse attach order, making manually stacked softraid volumes somewhat more practical. ok krw@
2013-01-18	The workunit completion needs to run at IPL_BIO, at least for now.	Joel Sing

2013-01-18	Tweak workunit completion.	Joel Sing

2013-01-18	Implement common workunit completion functions and handle the completion	Joel Sing
	via a workq callback. Also provide a discipline specific hook that allows it to optionally handle the final part of the workunit completion. ok krw@
2013-01-18	Reset I/O counters when releasing ccbs.	Joel Sing
	ok krw@
2013-01-16	Add a function that handles the completion of a ccb.	Joel Sing
	ok krw@
2013-01-16	Set resid to zero if the scsi transfer completed without error.	Joel Sing
	ok krw@
2013-01-16	Factor out code used to release ccbs from a workunit.	Joel Sing
	ok krw@
2013-01-15	Implement a function that gets and correctly initialises a ccb for I/O,	Joel Sing
	along with a function that enqueues a ccb on a workunit. ok krw@
2013-01-15	Keep a function pointer to the per-discipline I/O interrupt handler in the	Joel Sing
	discipline data structure. To be used with an upcoming diff.
2013-01-15	Factor out workunit initialisation code.	Joel Sing
	ok krw@
2012-10-09	Provide a mechanism for the kernel to directly pass a mask key through to	Joel Sing
	a crypto volume when it is assembling it.
2012-10-08	Provide a mechanism for the kernel to pass data through to the discipline	Joel Sing
	during volume assembly.
2012-10-08	Change handling for volumes that are marked no-auto assemble. If we booted	Joel Sing
	from the given volume ignore the no-auto assemble flag, since the root file system is located on it.
2012-10-08	bzero the right variable.	Joel Sing

2012-01-30	Prevent softraid from being used with devices that do not have a sector	Joel Sing
	size of 512 bytes - any other size is not currently supported. ok krw@
2012-01-28	Only pass bio ioctls through to the softraid bio ioctl handler. Rename the	Joel Sing
	handler to emphasise that it is for bio ioctls only. Discovered the hard way by dhill@
2012-01-22	Convert softraid(4) to new bio(4) status interface. This allows bioctl(8)	Joel Sing
	to provide useful feedback, rather than reporting an ioctl failure and leaving the user to consult dmesg. For now we continue to print most things to the console, even if the message is a result of an ioctl.
2012-01-22	Disable the softraid disk attach hook on detach.	Joel Sing

2012-01-22	Ensure that the sc_lock is held before the status functions are called.	Joel Sing

2012-01-21	Split sr_uuid_print() into two functions - one that formats and one that	Joel Sing
	prints. Also rename sr_uuid_get() to sr_uuid_generate().
2012-01-20	Add bio(4) status interface structs and utility functions to softraid(4).	Joel Sing

2012-01-17	Check the metadata level against the assembly level before proceeding with	Joel Sing
	any assembly. This avoids a panic when attempting to assemble a RAID 1 (or other) volume as a RAID 0 volume. Also reorder some of the other checks and diagnostics performed during assembly.
2012-01-17	Add missing ioctl DNPRINTFs and nuke some rogue commas.	Joel Sing

2012-01-11	Move softraid root mapping to later in the boot process - this will allow	Joel Sing
	us to play some tricks in setroot().
2012-01-11	Make sr_boot_chunk and sr_boot_volume accessible from userland. Add a	Joel Sing
	number of variables that are needed to detect and assemble volumes. A sr_metadata struct can be allocated and used via the sbc_metadata pointer, which we now do in the kernel boot probe/assembly code.
2011-12-31	Implement a concatenating discipline for softraid.	Joel Sing
	Many thanks to Marco Peereboom for his assistance with testing and debugging. Thanks also to Josh Grosse and Chris Jackman for testing.
2011-12-28	Cleanup the metadata initialisation process - have sr_meta_init()	Joel Sing
	initialise both the volume and chunk metadata before the discipline specific sd_create() function is called. The sr_meta_init_complete() function is then called to complete the initialisation based on values provided by sd_create().
