Author: pfg Date: Tue Jun 20 14:28:51 2017 New Revision: 320145 URL: https://svnweb.freebsd.org/changeset/base/320145
Log: ext2fs: Add uninit_bg feature support. From the linux tune2fs(8) manpage: "Allow the kernel to initialize bitmaps and inode tables and keep a high watermark for the unused inodes in a filesystem, to reduce e2fsck(8) time. This first e2fsck run after enabling this feature will take the full time, but subsequent e2fsck runs will take only a fraction of the original time, depending on how full the file system is."
