Merge patch series "vfs: if RESOLVE_NO_XDEV passed to openat2, don't *trigger* automounts"
Askar Safin <safinaskar@zohomail.com> says:
openat2 had a bug: if we pass RESOLVE_NO_XDEV, then openat2
doesn't traverse through automounts, but may still trigger them.
See this link for full bug report with reproducer:
https://lore.kernel.org/linux-fsdevel/20250817075252.4137628-1-safinaskar@zohomail.com/
This patchset fixes the bug.
RESOLVE_NO_XDEV logic hopefully becomes more clear:
now we immediately fail when we cross mountpoints.
