Alasdair G Kergon	5c6bd75d06	[PATCH] dm: prevent removal if open ... If you misuse the device-mapper interface (or there's a bug in your userspace tools) it's possible to end up with 'unlinked' mapped devices that cannot be removed until you reboot (along with uninterruptible processes). This patch prevents you from removing a device that is still open. It introduces dm_lock_for_deletion() which is called when a device is about to be removed to ensure that nothing has it open and nothing further can open it. It uses a private open_count for this which also lets us remove one of the problematic bdget_disk() calls elsewhere.

Darrick J. Wong	3ac51e741a	[PATCH] dm store geometry ... Allow drive geometry to be stored with a new DM_DEV_SET_GEOMETRY ioctl. Device-mapper will now respond to HDIO_GETGEO. If the geometry information is not available, zero will be returned for all of the parameters. Signed-off-by: Darrick J.

Alasdair G Kergon	6da487dcc0	[PATCH] device-mapper ioctl: add skip lock_fs flag ... Add ioctl DM_SKIP_LOCKFS_FLAG for userspace to request that lock_fs is bypassed when suspending a device. There's no change to the behaviour of existing code that doesn't know about the new flag.

Linus Torvalds	1da177e4c3	Linux-2.6.12-rc2 ... Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!	20 years ago
