+Subject: libmount: Fix atime remount for new API
+
+All atime settings are mutually exclusive, and the attr_set mask for
+the mount_setattr() syscall cannot contain multiple MOUNT_ATTR_ atime
+related options.
+
+Unfortunately, during a remount, the list of options is composed of
+both old and new options. In this case, libmount sets more atime
+options to the mask. The correct behavior is to use the last atime
+related option from the list.
+
+Fixes: https://github.com/util-linux/util-linux/issues/3032

+Subject: libsmartcols: fix reduction stages use
+
+There is no proper check for the number of reduction stages, so in
+some cases, the code can loop indefinitely.
+
+The patch also fixes 'rc' variable shadowing.

+Content-Transfer-Encoding: 8bit
+
+After fork() the memory of the calling thread is preserved into the new
+process. This also includes TLS.
+Make sure to reset the cache after a fork to avoid reuse of cached
+values.
+
+Only the TLS of the thread calling fork() is relevant as that is the
+only thread that gets forked.
+New threads will received newly initialized TLS.
