From: Josef Bacik Date: Tue, 2 Dec 2008 11:36:08 +0000 (-0500) Subject: Btrfs: add support for compat flags to btrfs X-Git-Tag: v2.6.29-rc1~27^2~9^2~38 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f2b636e80d8206dd4012de6e973c2367259a7d22;p=pandora-kernel.git Btrfs: add support for compat flags to btrfs This adds the necessary disk format for handling compatibility flags in the future to handle disk format changes. We have a compat_flags, compat_ro_flags and incompat_flags set for the super block. Compat flags will be to hold the features that are compatible with older versions of btrfs, compat_ro flags have features that are compatible with older versions of btrfs if the fs is mounted read only, and incompat_flags has features that are incompatible with older versions of btrfs. This also axes the compat_flags field for the inode and just makes the flags field a 64bit field, and changes the root item flags field to 64bit.
