[PATCH 0/2] Create io_uring fd with ephemeral inode

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

This set converts io_uring to use secure anon_inodes (with a newly allocated
non-S_PRIVATE inode) for each individual instance. In addition to allowing LSM
modules to enforce policy using the inode context, it also enables
checkpoint/restore usecases by allowing mapping the VMA to the open fd in a
task. Offset is already available to determine rings mapped per region, so this
was the only missing piece in establishing region <-> io_uring instance mapping.

LSM tie up has been left out of this set for now.
