Verification with bionic-proposed of xfstests results. No regressions introduced by this bcache patchset.
The comparison between -updates and -proposed is not directly possible because -proposed introduced failures via other components in I/O path (e.g., block, ext4). This is described below, and just to make sure, the -proposed kernel has been rebuilt with the bcache patchset reverted, and test results are the same (same failures with/without the patchset; no regression). It's also been confirmed (below) that tests with a raw block device (sda) instead of bcache device (thus eliminating the bcache code) shows the new/introduced failures (ext4/035, generic/553, generic/554). (the output below does look better on a very wide screen. :-) proposed kernel: 4.15.0-55.62 (with patchset) --- xfstests.test.none.log: Failures: ext4/032 ext4/035 generic/371 ----------- generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 xfstests.test.writearound.log: Failures: ext4/032 ext4/035 ----------- generic/451 generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 xfstests.test.writeback.log: Failures: -------- ext4/035 ----------- ----------- generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 xfstests.test.writethrough.log: Failures: ext4/032 ext4/035 ----------- ----------- generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 sda-only (no bcache) Failures: ext4/032 ext4/035 generic/371 ----------- generic/484 generic/491 ----------- ----------- generic/538 ----------- generic/553 generic/554 proposed kernel (4.15.0-56 without patchset) --- $ uname -rv 4.15.0-56-generic #62+test20190730b1 SMP Tue Jul 30 18:25:01 -03 2019 xfstests.test.none.log: Failures: ext4/032 ext4/035 generic/371 ----------- generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 xfstests.test.writearound.log: Failures: ext4/032 ext4/035 ----------- generic/451 generic/484 generic/491 ----------- generic/537 ----------- generic/547 generic/553 generic/554 xfstests.test.writeback.log: Failures: -------- ext4/035 ----------- ----------- generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 xfstests.test.writethrough.log: Failures: ext4/032 ext4/035 ----------- ----------- generic/484 generic/491 ----------- generic/537 ----------- ----------- generic/553 generic/554 test kernel (4.15.0-55 with patchset) --- xfstests.test.none.log: Failures: ext4/032 -------- ----------- ----------- generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- xfstests.test.writearound.log: Failures: ext4/032 -------- ----------- generic/451 generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- xfstests.test.writeback.log: Failures: -------- -------- ----------- ----------- generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- xfstests.test.writethrough.log: Failures: ext4/032 -------- ----------- ----------- generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- orig kernel (4.15.0-55) --- xfstests.test.none.log: Failures: ext4/032 -------- ----------- ----------- generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- xfstests.test.writearound.log: Failures: ext4/032 -------- generic/371 generic/451 generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- xfstests.test.writeback.log: Failures: -------- -------- ----------- ----------- generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- xfstests.test.writethrough.log: Failures: ext4/032 -------- ----------- ----------- generic/484 generic/491 generic/504 generic/537 ----------- ----------- ----------- ----------- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829563 Title: bcache: risk of data loss on I/O errors in backing or caching devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1829563/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
