The patch titled ext4: create /proc/ext4/*/stats et al more carefully has been removed from the -mm tree. Its filename was ext4-fix-11321-create-proc-ext4-stats-et-al-more-carefully.patch This patch was dropped because that file no longer has a bdevname call in it The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: ext4: create /proc/ext4/*/stats et al more carefully From: Alexey Dobriyan <adobriyan@xxxxxxxxx> Addresses http://bugzilla.kernel.org/show_bug.cgi?id=11321 ext4 creates per-suberblock directory in /proc/ext4/ . Name used as basis is taken from bdevname, which, surprise, can contain slash. However, proc while allowing to use proc_create("a/b", parent) form of PDE creation, assumes that parent/a was already created. bdevname in question is 'cciss/c0d0p9', directory is not created and all this stuff goes directly into /proc (which is real bug). Warning comes when _second_ partition is mounted.
