Thanks!

Funny, I thought about that today:-)
I prepared debian packaging for liburing-0.4 I'll send the patches soon.
While doing that I found the following incompatible change against
liburing-0.3:
static inline void io_uring_prep_files_update(struct io_uring_sqe *sqe,
- int *fds, unsigned nr_fds)
+ int *fds, unsigned nr_fds,
+ int offset)
I'm not sure if we should do something about that.
It's also strange that in src/liburing.map LIBURING_0.3 doesn't
inherit LIBURING_0.2. There's not a single symbol with @LIBURING_0.3.
Also io_uring_{setup,enter,register} are still
listed under LIBURING_0.1, but they're not in the library anymore.

I had the idea to have a simple version of fd compounding.
We already have IORING_OP_FILES_UPDATE in order to update
specific indexes in the files array.
I'm wondering if we could have specify an index where
IORING_OP_ACCEPT, IORING_OP_OPENAT and IORING_OP_OPENAT2
could store the generated fd into the fixed array.
The index 0 is not valid, correct? So we can have it
without a flag similar to the personality, and for
all of these buf_index is not used.
While researching that I noticed that IOSQE_FIXED_FILE
seems to be ignored for some new commands, I think that
all commands with on input fd, should be able to use that flag.
Can this be fixed before 5.6 final?
