Hi, Ian Kent and other autofs people. autofs.rst says: > mounting onto a directory is considered to be "beyond a `stat`" in https://elixir.bootlin.com/linux/v6.17-rc2/source/Documentation/filesystems/autofs.rst#L109 This is not true. Mounting does not trigger automounts. mount syscall ( https://elixir.bootlin.com/linux/v6.17-rc2/source/fs/namespace.c#L4321 ) calls "do_mount" ( https://elixir.bootlin.com/linux/v6.17-rc2/source/fs/namespace.c#L4124 ), which calls "user_path_at" without LOOKUP_AUTOMOUNT. This means automounts are not followed. I didn't test this, but I'm pretty sure about this by reading code. But what is worse, autofs.rst then proceeds to use this as an argument in favor of introducing DCACHE_MANAGE_TRANSIT! I. e. it seems that introducing DCACHE_MANAGE_TRANSIT rests on wrong premise. Thus, it seems (from reading autofs.rst) that DCACHE_MANAGE_TRANSIT and all accociated logic can be removed from kernel. -- Askar Safin https://types.pl/@safinaskar
