de37c802d7 o Targets now get rw passed through so they can do COW for example 
o Added error handler (not sure that this is the "correct" way to do
   this at the moment, so its a bit exprimental for now)

9b90e8ee2c o New ioctl(): LV_BMAP which is compatible with LVM so that hopefully LILO 
will work. I haven't actually tested that, but this support at least will
   be required.

df18917b3c Use dmfs_ function name prefix (in line with other file systems). 2001-09-14 13:27:58 +00:00

765d06119f o kmalloc error check 
o error file mode
The 1st Jan 1970 date I'm seeing in /dev is a devfs issue I think.

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.)

2565c99f8b o Use kmem_cache_destroy() to remove slab cache. 2001-09-13 11:07:08 +00:00

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.

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

bfba809c79 o added proper suspend/resume support, it now waits for all 'in flight' io's 
to complete.

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.
