[Bug 1846486] Re: revert the revert of ext4: make __ext4_get_inode_loc plug
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

** Description changed: == SRU Justification Eoan == Now that 5.4 contains a fix to the bootup regression due to the lack of entropy at bootable we should apply this fix and also revert the revert of commit "Revert "ext4: make __ext4_get_inode_loc plug"". == Fix == So, to clarify, apply the two upstream 5.4-rc commits: commit 50ee7529ec4500c88f8664560770a7a1b65db72b Author: Linus Torvalds Date: Sat Sep 28 16:53:52 2019 -0700 random: try to actively add entropy rather than passively wait for it commit 02f03c4206c1b2a7451d3b3546f86c9c783eac13 Author: Linus Torvalds Date: Sun Sep 29 17:59:23 2019 -0700 Revert "Revert "ext4: make __ext4_get_inode_loc plug"" - I've benchmarked the Eoan kernel with these two patches and found the - following speed improvements: + I've benchmarked the Eoan kernel with these two patches and found theo + following speed improvements on an i7-3770 CPU @ 3.40GHz with 8GB and a + WDC WD10EZEX-21WN4A HDD (7200RPM, 64MB cache). git grep of the kernel: 0.14% building fwts: 0.40% build stress-ng 0.45% tar up kernel source: 7.6% boot time of eoan cloud image: 10.5% So I think the speed improvements justify the SRU. == Regression potential == minor change to ext4, which has been regression tested, so risk here is small. The entropy change will alter the random number generation, but I believe this does not change the cryptographical security of the random numbers being generated, so think this change is not security risk. originally the ext4 change caused boot time user space regressions because of the entropy change of this fix, but the random fix addresses this, so I believe this risk is now zero. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846486 Title: revert the revert of ext4: make __ext4_get_inode_loc plug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1846486/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
