From 7484839850d826e14b8b024bb048dca8489140ae Mon Sep 17 00:00:00 2001 From: Maxim Shchetynin Date: Wed, 2 Apr 2008 00:12:20 +1100 Subject: [PATCH] [POWERPC] Fix rtas_flash procfs interface Handling of the proc_dir_entry->count was changed in 2.6.24-rc5. After this change, the default value for pde->count is 1 and not 0 as before. Therefore, if we want to check whether our procfs file is already opened (already in use), we have to check if pde->count is greater than 2 rather than 1.
