Subject: [PATCH 0/5] io_uring: add opcodes for current working directory

This provides consistency between io_uring and the respective I/O syscall
and avoids having the user of liburing specify the cwd in sqe when working
with current working directory, for e.g. the user can directly call with
IORING_OP_RENAME instead of IORING_OP_RENAMEAT and providing AT_FDCWD in
sqe->fd and sqe->len, similar to syscall interface.

This is done for rename, unlink, mkdir, symlink and link in this
patch-series.

The tests for these opcodes in liburing are present at
https://github.com/uarif1/liburing/tree/cwd_opcodes. If the patches are
acceptable, I am happy to create a PR in above for the tests.

Thanks!
