also be used to enable or disable barriers, for
consistency with other ext3 mount options.
-orlov (*) This enables the new Orlov block allocator. It is
- enabled by default.
-
-oldalloc This disables the Orlov block allocator and enables
- the old block allocator. Orlov should have better
- performance - we'd like to get some feedback if it's
- the contrary for you.
-
user_xattr Enables Extended User Attributes. Additionally, you
need to have extended attribute support enabled in the
kernel configuration (CONFIG_EXT3_FS_XATTR). See the
