Author: pfg Date: Sat Jan 11 15:19:04 2014 New Revision: 260545 URL: http://svnweb.freebsd.org/changeset/base/260545 Log: ext2fs: fix inode flag conversion. After r252890 we are naively attempting to pass through the inode flags. This is technically incorrect as the ext2 inode flags don't match the UFS/system values used in FreeBSD and a clean conversion is needed. Some filtering was left in place so the change didn't cause significant changes in FreeBSD but some of the garbage passed is likely to be the cause for warning messages in linux. Fix the issue by resetting the flags before conversion as was done previously. This also means we will not pass the EXT4_* inode flags into FreeBSD's inode.
