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- disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.
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. Thank you! ** Tags added: verification-needed-disco -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1837223 Title: shiftfs: add O_DIRECT support Status in linux package in Ubuntu: Fix Released Status in linux source package in Disco: Fix Committed Bug description: SRU Justification Impact: Currently shiftfs does not handle O_DIRECT if the underlay supports it. This is blocking dqlite - an essential part of LXD - from profiting from the performance benefits of O_DIRECT on suitable filesystems when used with async io such as aio or io_uring. Regression Potential: Limited to shiftfs and virtually none since we have not supported this feature before. Test Case: Run LXD with dqlite on a kernel that has support for shiftfs with O_DIRECT. Target Kernels: All LTS kernels with shiftfs support.
