Steven Whitehouse	b28dfc0655	o Fixed a bug where we were not holding a reference of the block devices ... used by the targets correctly.	2001-09-19 14:54:44 +00:00

Alasdair Kergon	7c913930fe	Error checking: only allow block devices & test for 'nodev'.	2001-09-17 21:17:30 +00:00
Steven Whitehouse	dea83b3f4c	o Use count should be an atomic_t	2001-09-17 09:01:23 +00:00
Steven Whitehouse	9f1da34243	o As promised earlier, the device registration is now hashed and the ... lists are private to dm-blkdev.c	2001-09-14 11:25:51 +00:00
Steven Whitehouse	e6b6c6a9cf	o Forgot to create slab caches for dm-blkdev.c ... o Misc code tidy	2001-09-14 10:40:20 +00:00
Steven Whitehouse	fd36a66ccc	Changes to device handling; ... o Only one list of block devices for all tables o Locking to ensure that block devices only get opened once o Block device handling is now in dm-blkdev.c o We open block devices when we create the tables and hold them open until the table is destroyed (this prevents the module for the device being unloaded after table parsing and before the table is used) o We compute the hardsect size when the table is created rather than when someone requests it. Still to fix/change: o Probably want to hash the device lists in dm-blkdev.c and also remove refs to struct dm_bdev outside this file. o Need to ensure that hardsect_size doesn't change when new tables are swapped in (maybe this ought to be a per volume parameter and the tables will only parse if they match the value for the volume?). Things are changing fast here, so if you want a stable version of thic code try checking out yesterdays.	2001-09-14 09:45:35 +00:00
Steven Whitehouse	31e6faf89f	o New code for handling block device registration. Not yet used but checked ... in for backup purposes.	2001-09-14 08:06:02 +00:00
