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

tkusumi | branches: 1.23.2; 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: Style cleanups (no functional changes)
|
1.21 |
| 15-Dec-2019 |
tkusumi | dm: Make targets' ->secsize() optional
and make a caller assume secsize 0 if ->secsize not present. This allows a dummy function to be removed which was added in "dm: Add dummy target ->sync()/->secsize() to prevent panic on modload(8)".
|

| 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. taken-from: DragonFlyBSD
|

| 12-Dec-2019 |
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). taken-from: DragonFlyBSD
|

| 08-Dec-2019 |
tkusumi | dm: Add dummy target ->sync()/->secsize() to prevent panic on modload(8)
dm_target_insert() has assertions to ensure targets implement all handlers. Adding dummy ones at least prevents panic on modload(8).
|
1.16 |
| 08-Dec-2019 |
tkusumi | dm: Move targets specific structs to .c files
These don't need to be defined and exposed in dm.h.
|
1.15 |
| 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: Fix strange pointer declarations
Should be "type *name" or "type* name", but not "type * name". taken-from: DragonFlyBSD
|

| 06-Dec-2019 |
tkusumi | dm: Don't ignore dm_target_alloc() argument
dm_target_alloc() is supposed to be copying the name argument to its ->name. taken-from: DragonFlyBSD
|
1.12 |
| 05-Dec-2019 |
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.
taken-from: DragonFlyBSD
|
1.11 |
| 01-Dec-2019 |
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.

1.10 |
| 05-Jan-2018 |
christos | branches: 1.10.4; use some size_t, add whitespace between functions, rcsids.
|
1.9 |
| 18-May-2010 |
haad | Add support for DIOCCACHESYNC ioctl for dm devices. Add new sync function pointer to dm_target_t because that is the only part of dm which know real block device. disk_ioctl_switch parses whole device table and for every entry it calls particular sync routine which propagates DIOCCACHESYNC to real disk.
While I was here implement some KNF fixes and remove unneeded symbols from dm.h.
Problem reported on port-xen@ by Hugo Silva.

| 04-Jan-2010 |
haad | branches: 1.8.2; 1.8.4; Indent files remove unnecessary blank lines, white spaces and KNFize code.
|
1.7 |
| 01-Dec-2009 |
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.

1.6 |
| 05-Jun-2009 |
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.

1.5 |
| 01-Mar-2009 |
haad | branches: 1.5.2; Change comment and add description of line used to configure mirror device.
|
1.4 |
| 19-Feb-2009 |
haad | Add support for autoloading of device-mapper targets modules. Add dm_target_autoload function which tries to load target module. Fix two deadlocks in dm_table_load_ioctl error path(I forgot to call dm_dev_unbusy).
|
1.3 |
| 14-Jan-2009 |
haad | branches: 1.3.2; 1.3.4; 1.3.6; Add dm module as dependency and remove module_hold/module_rele calls.
|
1.2 |
| 02-Jan-2009 |
haad | Return ENOSYS during from dm_target_init routine these tow targets aren't implemented yet.
|
1.1 |
| 02-Jan-2009 |
haad | Add stubs for mirror target, too. This target does nothing for now, but lvm tools support mirror target and trying to create LV with mirrorred backend caused panic in dm_table_load_ioctl.
