Aditya Kali 1c8457cadc ext4: avoid uneeded calls to ext4_mb_load_buddy() while reading mb_groups ... Currently ext4_mb_load_buddy is called for every group, irrespective of whether the group info is already in memory, while reading /proc/fs/ext4/<partition>/mb_groups proc file. For the purpose of mb_groups proc file, it is unnecessary to load the file group info from disk if it was loaded in past. These calls to ext4_mb_load_buddy make reading the mb_groups proc file expensive. Also, the locks around ext4_get_group_info are not required. This patch modifies the code to call ext4_mb_load_buddy only if the group info had never been loaded into memory in past. It also removes the mb group locking around ext4_get_group_info call.
