-Subject: [PATCH] libmount: remove read-mountinfo workaround
-
-This workaround has been introduced by
-http://github.com/karelzak/util-linux/commit/e4925f591c1bfb83719418b56b952830d15b77eb
-
-And originally requested by https://github.com/systemd/systemd/issues/10872
-
-It seems we do not need it anymore as the problem should be fixed in kernel since 5.8
-(kernel commit 9f6c61f96f2d97cbb5f7fa85607bc398f843ff0f).
-
-Note that the libmount solution is very expensive as it repeats read()
-many times (until we get consistent result) if kernel is busy with
-mount table modification. This behaviour makes events management in
-systemd (or other places) pretty difficult as read mountinfo takes
-time on busy systems.
-
-Addresses: https://github.com/systemd/systemd/pull/16537
-Signed-off-by: Karel Zak <kzak@redhat.com>
