Subject: [PATCH] io_uring: bump max direct descriptor count to 1M
Git-commit: 09893e15f1e9910711c152cd126ccfa85581ba83
Patch-mainline: v5.19-rc1
References: bsc#1205205

We currently limit these to 32K, but since we're now backing the table
space with vmalloc when needed, there's no reason why we can't make it
bigger. The total space is limited by RLIMIT_NOFILE as well.
