From: Chris Mason Date: Thu, 2 Jul 2009 16:26:06 +0000 (-0400) Subject: Btrfs: honor nodatacow/sum mount options for new files X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9427216476d4fa75103f39d4b228c47d56ba20da;p=openwrt%2Fstaging%2Fblogic.git Btrfs: honor nodatacow/sum mount options for new files The btrfs attr patches unconditionally inherited the inode flags field without honoring nodatacow and nodatasum. This fix makes sure we properly record the nodatacow/sum mount options in new inodes.
