Ok, that's on vfs.netfs for now. It's based on vfs.rw as that has splice
changes that would cause needless conflicts. It helps to not have such
series based on -next.
Fwiw, I'd rather have this based on a mainline tag in the future. Linus
has stated loads of times that he doesn't mind handling merge conflicts
and for me it's a lot easier if I have a stable mainline tag. linux-next
is too volatile. Thanks!
---
Applied to the vfs.netfs branch of the vfs/vfs.git tree.
Patches in the vfs.netfs 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.
