tkusumi | dm: #if0 target's ->upcall() handler
This is part of NetBSD's dm design, but unimplemented
(all handlers return 0) and also unused.

dm: Fix dm-stripe's "status" output format
As mentioned in "dm: Don't try to implement "status" as subset of "table"",
dm-stripe in NetBSD doesn't have correct "status" output format.
Implement ->info() to sync with Linux kernel.
Note that num_error for stripe device isn't implemented yet.

tkusumi | dm: Remove target's ->deps() by implementing deps in dm core
Retrieving device dependencies doesn't need to be target specific.
The reason it currently needs ->deps() is because dm core doesn't
have data structure that allows table to walk through target's
underlying devices. Add struct dm_mapping to be able to do this,
and remove ->deps()'s from targets which basically do the same thing.

tkusumi | dm: Fix "table" output format of dm-linear and dm-stripe
The existing "table" output showing device file path of pdev is
not compatible with dm in Linux kernel (and also DragonFlyBSD).
It should be showing "major:minor" instead.

tkusumi | dm: Test # of args in target's ->init()
The # of args is part of target's spec.
Both Linux kernel and DragonFlyBSD test argc on ctr/init.

tkusumi | dm: Rename dm specific atoi() to atoi64()
This is uint64_t version, not sys/lib/libsa/atoi.c.

tkusumi | dm: Style cleanups (no functional changes)
|
| 1.37 |

tkusumi | dm: "unsigned" -> "unsigned int" for consistency
Use either one, but not both.
|

| 15-Dec-2019 |
tkusumi | dm: Rename targets' ->status() to ->table() given ->info() exists
Since now that dm targets in NetBSD have ->info() for "status",
->status() should be renamed to ->table() for "table",
given how dm target status was originally designed in Linux kernel.

tkusumi | dm: Remove unconditional debug prints in targets' ->strategy()
Having debug prints in ->strategy() by default just to tell ->strategy()
is called is overkill.

tkusumi | dm: Make target's ->init() take parsed argc and argv
This gets rid of the same parser code in each target using strsep(3).

| 1.33 |
| 09-Dec-2019 |
tkusumi | dm: Correct target name "stripe" -> "striped"
Sync with Linux kernel.
The file name is "stripe", but the target name is "striped".
DragonFlyBSD also follows this.

| 1.32 |
| 08-Dec-2019 |
tkusumi | dm: Move targets specific structs to .c files
These don't need to be defined and exposed in dm.h.
|

| 08-Dec-2019 |
tkusumi | dm: Refactor target's ->init() i/f
Take dm_table_entry_t* instead of void**.
Remove dm_dev_t* unneeded by target code.
No functional change, but for future changes.

tkusumi | dm: Make dm core set config to NULL after destroy
Just let dm core do this instead of having a comment expecting each
target to do the right thing.

tkusumi | dm: Include <sys/vnode.h> in dm.h
dm.h already depends on vnode, so have dm.h include <sys/vnode.h>
instead of other .c files.

tkusumi | dm: Remove unused dm_dev::dev_type
Given OOP-like architecture of dm target device structure,
dm_dev doesn't need to have self contained target type field,
and in fact this is unused.

chs | remove checks for failure after memory allocation calls that cannot fail:
kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

hannken | branches: 1.19.2;
Change dk_lookup() to return an anonymous vnode not associated with
any file system. Change all consumers of dk_lookup() to get the
device from "v_rdev" instead of VOP_GETATTR() as specfs does not
support VOP_GETATTR(). Devices obtained with dk_lookup() will no
longer disappear on forced unmounts.

Change the vnode locking protocol of VOP_GETATTR() to request at least
a shared lock. Make all calls outside of file systems respect it.
The calls from file systems need review.
No objections from tech-kern.

mlelstv | branches: 1.13.2; 1.13.6;
make dm aware of physical sector sizes.
For aggregates of multiple disks we use the largest sector size from
all disks. For standard power-of-2 sizes this is the same as the least
common multiple. We still require proper alignment of the targets in
the mapping table.

haad | Revert my commit which have added knowledge about dm targets to libdevmapper,
this breaks abstraction. Because only lvmtools/lvmlib and device-mapper can
have knowledge about target mapping and libdevmapper only passes requests
from lvmtools to kernel and back. Bump major library and driver version.

haad | Fix bug in kmem_alloc/kmem_free of params string. Params string was
allocated with length DM_MAX_PARAMS_SIZE and released with strlen + 1 size.
Disable KM_NOSLEEP allocation because we do not need them here there is
nothing critical in ioctl part of dm driver.
Bug reported by jak@.

haad | Parse dm param string in libdevmapper and not in a dm target init function.
Create proplib param dictionary entry in libdevmapper and pass it to dm in
dm_ioctl dict.
Param target is then passed to target init function, where is parse. I like
this aproach much better than passing char **argv and trusting to user input.
I have bumped minor lib/driver version.
XXX. Add more sanity checks in kernel.

haad | Add initial support for striping target, hardcode maximal number of stripes
to 2 for now. strategy routine must be written, for now only parsing and
support routines are available. This is work in progress code and should be
taken very carefully.

haad | Add stripe target functions stubs. Stripe target must be present in dm driver
because without it lvm2tools will not create LVsi and eventualy panic system.
