Hi Jens,
The bcache has 4 patches for Linux v5.19 merge window, all from me.
- The first 2 patches are code clean up and potential bug fixes for
multi- threaded btree nodes check (for cache device) and dirty sectors
counting (for backing device), although no report from mailing list for
them, it is good to have the fixes.
- The 3rd patch removes incremental dirty sectors counting because it
is conflicted with multithreaded dirty sectors counting and the latter
one is 10x times faster.
- The last patch fixes a journal no-space deadlock during cache device
registration, it always reserves one journal bucket and only uses it
in registration time, so the no-spance condition won't happen anymore.
There are still 2 fixes are still under the long time I/O pressure
testing, once they are accomplished, I will submit to you in later
RC cycles.
Please take them, and thanks in advance.
