| | * | | | drbd: new on-disk activity log transaction formatLars Ellenberg2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a new on-disk transaction format for the activity log, which allows for multiple changes to the active set per transaction. Using 4k transaction blocks, we can now get rid of the work-around code to deal with devices not supporting 512 byte logical block size.

| | * | | | lru_cache: allow multiple changes per transactionLars Ellenberg2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow multiple changes to the active set of elements in lru_cache. The only current user of lru_cache, drbd, is driving this generalisation. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
| | * | | | drbd: allow to select specific bitmap pages for writeoutLars Ellenberg2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are about to allow several changes to the active set in one activity log transaction. We have to write out the corresponding bitmap pages as well, if changed. Introduce drbd_bm_mark_for_writeout(), then re-use the existing bitmap writeout path to submit all marked pages in one go.

| | * | | | drbd: use clear_bit_unlock() where appropriateLars Ellenberg2011-10-14

| | * | | | drbd: in drbd_suspend_al, set AL_SUSPENDED before unlocking the activity logLars Ellenberg2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As using an empty activity log is the whole point of the excercise, make sure it is still empty when setting AL_SUSPENDED.
