fee7b9e6a5 o Now we handle target modules correctly
o Moved the linear target into its own module (not really because it needs to
   be there, but because its useful to have a simple example so people can see
   what we are doing)

Btw, this needs testing properly.

576d347777 o Some structures change size with different configs, so always include

5c8de1dbd5 o I'm afraid that wu and wl etc. is just too confusing.... I've changed it
to up_write() and down_write() etc so that you can see what kind of a lock
   it is (otherwise it could be anything.. semaphore, spinlock, spinlock_bh,
   spinlock_irq, br_lock, etc.)

3f03a60736 o first sattab at custom fs. Very rough ATM.
Mount the dm-fs filesystem on /device-mapper (will fix later).  mkdir
to create a device, inside that directory every file you create is a table
file.  If there are errors <table>.err will appear automagically.  Mv a table
file to ACTIVE to activeate the device.  I'm not happy with mv being the
binding command, symlink would be better.

e69ce84e34 o Added two new functions get_child [Andrew Clausen] and get_node. I think
this makes 'high()' a bit more understandable.

a46d94071b o added reference counting to the destination devices, make sure that the
destructor for any targets you write call dm_table_remove_device.
2001-08-31 16:36:56 +00:00
Joe Thornber
0f29dc2f2d o split struct mapped_device into mapped_device and dm_table
o seperated loading of a table from binding a table to the device

These should allow multiple tables to be managed by dm-fs

Steven Whitehouse
9404455a07 dec use count on close. corrects a typo.
Really the use counts on these modules should be handled at a higher level,
otherwise there are races I think.
