[PATCH 0/4] uapi, vfs: Change the mount API UAPI

From: David Howells
Date: Thu May 16 2019 - 07:25:36 EST



Hi Linus, Al,

Here are some patches that make changes to the mount API UAPI and two of
them really need applying, before -rc1 - if they're going to be applied at
all.

The following changes are made:

(1) Make the file descriptors returned by open_tree(), fsopen(), fspick()
and fsmount() O_CLOEXEC by default and remove the flags that allow
this to be specified from the UAPI, shuffling other flags down as
appropriate. fcntl() can still be used to change the flag.

(2) Make the name of the anon inode object "[fscontext]" with square
brackets to match other users.

(3) Fix the numbering of the mount API syscalls to be in the common space
rather than in the arch-specific space.

(4) Wire up the mount API syscalls on all arches (it's only on x86
currently).

Thanks,
David
