Thank you!
Hi Linus, Please pull this branch with changes for xfs for 6.3-rc1. This second pull request contains a fix for a deadlock in the allocator. It continues the slow march towards being able to offline AGs, and it refactors the interface to the xfs allocator to be less indirection happy. As usual, I did a test-merge with the main upstream branch as of a few minutes ago, and didn't see any conflicts. Please let me know if you encounter any problems. --D The following changes since commit dd07bb8b6baf2389caff221f043d9188ce6bab8c: xfs: revert commit 8954c44ff477 (2023-02-10 09:06:06 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-6.3-merge-4 for you to fetch changes up to 6e2985c938e8b765b3de299c561d87f98330c546: xfs: restore old agirotor behavior (2023-02-27 08:53:45 -0800) ---------------------------------------------------------------- New code for 6.3-rc1, part 2: * Fix a deadlock in the free space allocator due to the AG-walking algorithm forgetting to follow AG-order locking rules. * Make the inode allocator prefer existing free inodes instead of failing to allocate new inode chunks when free space is low. * Set minleft correctly when setting allocator parameters for bmap changes. * Fix uninitialized variable access in the getfsmap code. * Make a distinction between active and passive per-AG structure references. For now, active references are taken to perform some work in an AG on behalf of a high level operation; passive references are used by lower level code to finish operations started by other threads. Eventually this will become part of online shrink. * Split out all the different allocator strategies into separate functions to move us away from design antipattern of filling out a huge structure for various differentish things and issuing a single function multiplexing call. * Various cleanups in the filestreams allocator code, which we might very well want to deprecate instead of continuing. * Fix a bug with the agi rotor code that was introduced earlier in this series.
