So + we need to backport the following upstream patch. https://git.kernel.org/pub/scm/linux/storage/autofs/autofs.git/commit/?id=67e7d613a4b09eeffc57ab44a7acb52027d897b2 - [1] https://bugzilla.redhat.com/show_bug.cgi?id=1440769 + [Test Case] + + * Create an autofs direct mount map with large direct mappings (eg: + more than 20k) + + * Start autofs service to see if it will take too much time to + automount all mappings. + + [Regression Potential] + + With this upstream patch, we can avoid creating path compnents on remote + file system unless that file system is the root file system. so + theoretically there is no regression potential. + + [Other Info] + + Redhat [1] also already backported the following patch, see: https://bugzilla.redhat.com/show_bug.cgi?id=1440769
