Support for random access file reads

[Tim Fox <tfox@xxxxxxxxxxxx>]

Hello folks,

I am new to io-uring and would like to read bytes from a specific
position in a file. I was looking for some kind of pread/preadv
functionality in io-uring but couldn't see any.

Perhaps the expectation that the file descriptor offset is explicitly
set via lseek outside of io-uring, to enable random file access use
cases like mine?

Thanks
