Hi Jens, Here are 12 patchs for bcache fixes and updates, most of them were posted by Eric Wheeler in 4.13 merge window, but delayed due to lack of code review. The following patches are reviewed or acked by peer developers, 0001-bcache-Fix-leak-of-bdev-reference.patch 0002-bcache-fix-sequential-large-write-IO-bypass.patch 0003-bcache-do-not-subtract-sectors_to_gc-for-bypassed-IO.patch 0004-bcache-Don-t-reinvent-the-wheel-but-use-existing-lli.patch 0005-bcache-gc-does-not-work-when-triggering-by-manual-co.patch 0006-bcache-correct-cache_dirty_target-in-__update_writeb.patch 0007-bcache-Correct-return-value-for-sysfs-attach-errors.patch 0008-bcache-increase-the-number-of-open-buckets.patch 0009-bcache-fix-for-gc-and-write-back-race.patch 0010-bcache-silence-static-checker-warning.patch 0011-bcache-Update-continue_at-documentation.patch 0012-bcache-fix-bch_hprint-crash-and-improve-output.patch You may consider to pick them up if no other comments come up, especially 0012-bcache-fix-bch_hprint-crash-and-improve-output.patch which fixes a potential serious security issue as author declears. I do basic test on the whole patch set, bcache works and behaves as expected. For futher bcache bug reports, I will follow up them. There are some other patches which does not pass my test currently, once they are fixed and reviewed by peer developers I will send them to you for 4.14 merge window. Thanks in advance. Coly Li
