+Subject: [PATCH] virfile: Fix build with glibc 2.36
+
+With glibc 2.36, sys/mount.h and linux/mount.h conflict:
+https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3E
+
+virfile.c imports sys/mount.h and linux/fs.h, which pulls in
+linux/mount.h.
+
+Manually define the constants we need from linux/fs.h, like was
+done in llvm:
