+Subject: [PATCH 1/2] ls: avoid triggering automounts
+
+statx() has different defaults wrt automounting
+compared to stat() or lstat(), so explicitly
+set the AT_NO_AUTOMOUNT flag to suppress that behavior,
+and avoid unintended operations or potential errors.
+
+* src/ls.c (do_statx): Pass AT_NO_AUTOMOUNT to avoid this behavior.
+Fixes https://bugs.gnu.org/54286

+Subject: [PATCH 2/2] stat: only automount with --cached=never
+
+Revert to the default behavior before the introduction of statx().
+
+* src/stat.c (do_stat): Set AT_NO_AUTOMOUNT without --cached=never.
+* doc/coreutils.texi (stat invocation): Mention the automount
+behavior with --cached=never.
