[GIT PULL] io_uring fixes for 5.11-rc1

[Jens Axboe]

Hi Linus,

Fixes that should go into 5.11-rc1. All straight fixes, or a prep patch
for a fix, either bound for stable or fixing issues from this merge
window. In particular:

- Fix new shutdown op not breaking links on failure

- Hold mm->mmap_sem for mm->locked_vm manipulation

- Various cancelation fixes (me, Pavel)

- Fix error path potential double ctx free (Pavel)

- IOPOLL fixes (Xiaoguang)

Please pull!
