[Ocfs2-devel] a puzzle about is_global_system_inode function

[alex chen]

Hi Larry Chen,

I think the reason is because the GLOBAL_INODE_ALLOC_SYSTEM_INODE
is just used when the device is offline, such as used in mkfs.ocfs2
and tunefs.ocfs2, it is not needed when the device is online.

Thanks
Alex
