I just found this:
+ {OCFS2_FEATURE_COMPAT_BACKUP_SB | OCFS2_FEATURE_COMPAT_JBD2_SB,
+ OCFS2_FEATURE_INCOMPAT_SPARSE_ALLOC |
+ OCFS2_FEATURE_INCOMPAT_INLINE_DATA |
+ OCFS2_FEATURE_INCOMPAT_XATTR |
+ OCFS2_FEATURE_INCOMPAT_REFCOUNT_TREE,
+ OCFS2_FEATURE_RO_COMPAT_UNWRITTEN}, /* FS_VMSTORE */
These options are the ones that, when choosing for vmstore, are
enabled by default. Is this correct?
Thanks.
