+Subject: [PATCH] Fix glibc 2.36 build (mount.h conflicts)
+
+glibc has decided that sys/mount.h and linux/mount.h are no longer
+usable at the same time.  This broke the build, since linux/fs.h itself
+includes linux/mount.h.  For now, fix the build by only including
+sys/mount.h where we need it.
+
+See-also: https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3E
+Resolves: #227
+
+Upstream-Status: Backport [https://github.com/rhboot/efivar/commit/bc65d63ebf8fe6ac8a099ff15ca200986dba1565]
