Hi Jens,

Here are the patches for Linux v4.21.

The patches from me are for a set of disabled-by-default optimization
for writeback cache mode, which are used by some users I know. Guoju
Fang contributes a patch to add number of keys in
trace_bcache_journal_write(). And there are 6 patchges are from Shenghui
Wang, which removes an unncessary NULL check for
debugfs_remove_recursive() and debugfs_remove(), adds useful code
comments for bcache, and improves sysfs information display for bcache
writeback rate parameters.

We don't have important or big change in this run. Please take these
patches.

Thanks in advance.
