Subject: [PATCH V2 1/2] f2fs: A minor change for avoiding any possible conflicts
 to the other fs

From: Younger Liu <liuyiyang@...ense.com>

This minor change for the naming conventions of debugfs_root
to avoid any possible conflicts to the other filesystem.

This patch is based on the first patch:
[PATCH V2 0/2] f2fs: remove debufs dir if debugfs_create_file() failed.
