+Subject: [PATCH 2/2] criu: fix conflicting headers
+
+There are several changes in glibc 2.36 that make sys/mount.h header
+incompatible with kernel headers:
+
+https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3E
+
+This patch removes conflicting includes for `<linux/mount.h>` and
+updates the content of `criu/include/linux/mount.h` to match
+`/usr/include/sys/mount.h`. In addition, inline definitions sys_*()
+functions have been moved from "linux/mount.h" to "syscall.h" to
+avoid conflicts with `uapi/compel/plugins/std/syscall.h` and
+`<unistd.h>`. The include for `<linux/aio_abi.h>` has been replaced
+with local include to avoid conflicts with `<sys/mount.h>`.
+
+Fixes: #1949
