liburing/barrier.h: Add prefix io_uring to barriers

2019-08-19T14:45:28+00:00

The names of the barriers conflict with the namespaces of other projects
when trying to directly include liburing.h. Avoid using popular global
names.

src/Makefile: keep private headers in

2019-07-24T15:11:44+00:00

It is not possible to install barrier.h and compat.h into the top-level
/usr/include directly since they are likely to conflict with other
software.  io_uring.h could be confused with the system's kernel header
file.

Put liburing headers into  so there is no chance of
conflicts or confusion.

Existing applications continue to build successfully since the location
of  is unchanged.  In-tree examples and tests require
modification because src/liburing.h is moved to src/include/liburing.h.

Makefiles: Support specifying CFLAGS on the command line

2019-07-08T21:25:57+00:00

This patch makes the liburing build work as expected for e.g. the following
command:

make CFLAGS=-m32

and avoids that the build fails as follows for the above command:

make[1]: Entering directory 'liburing/test'
cc -m32 -o poll poll.c -luring
/usr/bin/ld: cannot find -luring
collect2: error: ld returned 1 exit status
Makefile:18: recipe for target 'poll' failed
make[1]: *** [poll] Error 1
make[1]: Leaving directory 'software/liburing/test'
Makefile:12: recipe for target 'all' failed
make: *** [all] Error 2

Fix the use of memory barriers

2019-07-02T13:33:52+00:00

Introduce the smp_load_acquire() and smp_store_release() macros. Fix
synchronization in io_uring_cq_advance() and __io_uring_get_cqe().
Remove a superfluous local variable, if-test and write barrier from
__io_uring_submit(). Remove a superfluous barrier from
test/io_uring_enter.c.
