Lars Ellenberg authored
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. Signed-off-by:

In compatibility mode with old DRBDs, use that as the state_mutex as well. Signed-off-by:

Philipp Reisner authored
The lock they constructed is only taken when the state_mutex was already taken. It is superficial. Signed-off-by:
