Alasdair Kergon b849de1d18 Fix the device cache to cope reasonably safely with device name changes. ... This should be a rare occurrence so the aim is to recover if it's straightforward to do so, otherwise just to abort the operation. If people *knowingly* change device names, they should always run vgscan afterwards. A few bytes of memory gets leaked inside a pool each time an alias has to be discarded - it's not worth restructuring the code to reuse it. More of LVM2 needs updating to pass device objects (or uuids) about instead of pathnames so that resolution of pathname->object only happens once per operation. dev_cache_get() should now always return the *current* device at the path given dev_name_confirmed() replaces dev_name() whenever it's important to know that name for the device is still current (ie when opening it). If the cache doesn't know a current name, the function fails. dev_open() guarantees that the file descriptor returned is for the dev_t of the device structure it was passed.		2002-01-24 23:16:19 +00:00
