From b40cf0a490c28d5b79e05382d061983b92a7b2b3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Tue, 10 Jan 2023 12:37:25 -0500 Subject: [PATCH 4/7] 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 Signed-off-by: Daniel P.
