From 825f1481ead4ce40671089bae7412ac3519e8caa Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Fri, 15 Feb 2008 15:00:38 -0500 Subject: [PATCH] ext4: Don't use ext4_dec_count() if not needed The ext4_dec_count() function is only needed when dropping the i_nlink count on inodes which are (or which could be) directories. If we *know* that the inode in question can't possibly be a directory, use drop_nlink or clear_nlink() if we know i_nlink is 1.
