From 4589d25d015c2d02bb5f7075d0cbf6dcf23a33c0 Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Tue, 15 Jan 2013 19:58:47 +0900 Subject: f2fs: fix the debugfs entry creation path As the "status" debugfs entry will be maintained for entire F2FS filesystem irrespective of the number of partitions. So, we can move the initialization to the init part of the f2fs and destroy will be done from exit part. After making changes, for individual partition mount - entry creation code will not be executed.
