+Subject: [PATCH] Revert "linux-user: fix compat with glibc >= 2.36
+ sys/mount.h"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 3cd3df2a9584e6f753bb62a0028bd67124ab5532.
+
+glibc has fixed (in 2.36.9000-40-g774058d729) the problem
+that caused a clash when both sys/mount.h annd linux/mount.h
+are included, and backported this to the 2.36 stable release
+too:
+
+  https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3E
+
+It is saner for QEMU to remove the workaround it applied for
+glibc 2.36 and expect distros to ship the 2.36 maint release
+with the fix. This avoids needing to add a further workaround
+to QEMU to deal with the fact that linux/brtfs.h now also pulls
+in linux/mount.h via linux/fs.h since Linux 6.1
