------------------------------------------------------ From: Andy Shevchenko andriy.shevchenko@linux.intel.com Subject: Revert "um: Use swap() to make code cleaner" Date: Mon, 24 Jul 2023 17:31:31 +0300
This reverts commit 9b0da3f22307af693be80f5d3a89dc4c7f360a85.
The sigio.c is clearly user space code which is handled by arch/um/scripts/Makefile.rules (see USER_OBJS rule).
The above mentioned commit simply broke this agreement, we may not use Linux kernel internal headers in them without thorough thinking.
Hence, revert the wrong commit.
