These days what I have gotten is that the unmap_mapping_range() could
be used.
At the same time I have deep into the mm code and fixed the double
usage of
the data blocks and possible page fault call trace bugs mentioned above.
Following is the V3 patch. I have test this using 4 targets & fio for
about 2 days, so
far so good.
I'm still testing this using more complex test case.
I have test it the whole day today:
- using 4 targets
- setting TCMU_GLOBAL_MAX_BLOCKS = [512 1K 1M 1G 2G]
- each target here needs more than 450 blocks when running
- fio: -iodepth [1 2 4 8 16] -thread -rw=[read write] -bs=[1K 2K 3K 5K
7K 16K 64K 1M] -size=20G -numjobs=10 -runtime=1000 ...
Hi Xiubo,
V3 is sounding very good. I look forward to reviewing it after it is posted.
Thanks -- Regards -- Andy
