Patches in the vfs.fixes branch should appear in linux-next soon. Please report any outstanding bugs that were missed during review in a new review to the original patch series allowing us to drop it. It's encouraged to provide Acked-bys and Reviewed-bys even though the patch has now been applied. If possible patch trailers will be updated. Note that commit hashes shown below are subject to change due to rebase, trailer updates or similar. If in doubt, please check the listed branch. tree: https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git branch: vfs.fixes [1/2] block: handle BLK_OPEN_RESTRICT_WRITES correctly https://git.kernel.org/vfs/vfs/c/ddd65e19c601 [2/2] block: count BLK_OPEN_RESTRICT_WRITES openers https://git.kernel.org/vfs/vfs/c/3ff56e285de5
