Patches in the vfs-6.14.misc 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.

Fix the return type of do_mount() function from long to int to match its ac tual behavior. The function only returns int values, and all callers, inclu ding those in fs/namespace.c and arch/alpha/kernel/osf_sys.c, already treat the return value as int. This change improves type consistency across the filesystem code and aligns the function signature with its existing impleme ntation and usage.
