Subject: [PATCH] io_uring: add header include guards to all header files
Date: Tue, 17 Jun 2025 11:50:01 -0700	[thread overview]
Message-ID: <20250617185001.1782992-1-vishs@meta.com> (raw)

From: Vishwanath Seshagiri <vishs@fb.com>

Add missing header include guards to all *.h files in the io_uring/
directory to prevent multiple inclusion issues. This follows the
established pattern used in io_uring/zcrx.h and other kernel headers.

The guards use the format IOU_<NAME>_H to maintain consistency with
the io_uring subsystem naming conventions.

Testing: Verified functionality with liburing test suite - all tests pass.
