Hi Jens, Please pick up the following patches. - Hans reworked the write error recovery path in pblk. - Igor added extra error handling for lines, and fixed a bug in the pblk ringbuffer during GC. - Javier refactored the pblk code a bit, added extra error handling, and added checks to verify that data returned from drive is appropriate. - Marcin added some extra logic to manage the write buffer. Now MW_CUNITS can be zero and the size of write buffer can be changed at module load time.
