drbd: Concurrent write detection fix · 206d3589

由 Andreas Gruenbacher 提交于 2月 26, 2011

Commit 9b1e63e changed the concurrent write detection algorithm to only insert
peer requests into write_requests tree after determining that there is no
conflict. With this change, new conflicting local requests could be added
while the algorithm runs, but this case was not handled correctly. Instead of
making the algorithm deal with this case, switch back to adding peer requests
to the write_requests tree immediately: this improves fairness.

When a peer request is discarded, remove that request from the write_requests

drbd: new on-disk activity log transaction format · 7ad651b5

由 Lars Ellenberg 提交于 2月 21, 2011

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.

drbd: allow to select specific bitmap pages for writeout · 45dfffeb

由 Lars Ellenberg 提交于 2月 21, 2011

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.
