Starting with this release. These +changes should be internal rather than having a big effect on +the command line. Inevitably these changes will increase the +chance of bugs, so please be on the alert. + + +Remove support for obsolete metadata formats +-------------------------------------------- + +Support for the GFS pool format, and format used by the +original 1990's version of LVM1 have been removed. + +Use asynchronous IO +------------------- + +Almost all IO uses libaio now. + +Rewrite label scanning +---------------------- + +Dave Tiegland has reworked the label scanning and metadata reading +logic to minimise the amount a IOs issued. Combined with the aio changes +this can greatly improve scanning speed for some systems. + +./configure options +------------------- + +We're going to try and remove as many options from ./configure as we +can. Each option multiplies the number of possible configurations +that we should test (this testing is currently not occuring). + +The first batch to be removed are: + + --enable-testing switch for ./configure has been removed. + --with-snapshots switch for ./configure has been removed. + --with-mirrors switch for ./configure has been removed. + --with-raid switch for ./configure has been removed. + --with-thin switch for ./configure has been removed. + --with-cache switch for ./configure has been removed. + +Stable targets that are in the upstream kernel will just be supported. + +In future optional target flags will be given in two situations: + +1) The target is experimental, or not upstream at all (eg, vdo). +2) The target is deprecated and support will be removed at some future date. + +This decision could well be contentious, so could distro maintainers feel +free to comment.
