From: Jaegeuk Kim Date: Tue, 26 Nov 2013 02:08:57 +0000 (+0900) Subject: f2fs: add the number of inline_data files to status info X-Git-Tag: firefly_0821_release~176^2~4598^2~22 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0dbdc2ae9bba0a358816cc4a22e41a6ef16db8a2;p=firefly-linux-kernel-4.4.55.git f2fs: add the number of inline_data files to status info This patch adds the number of inline_data files into the status information. Note that the number is reset whenever the filesystem is newly mounted.
