...So while we still want to ask for a minimum number of bits equal to window size, there is no reason why we should limit the number of bits the local alloc should accept. Hence always allow the maximum number of local alloc bits.

Hi, All, These four patches are all related to ocfs2 on hard readonly mount. patch 1 fix oops when umount ocfs2 on hard readonly device. Because ocfs2_dismount_volume() will call ocfs2_cluster_hangup() and then call ocfs2_stack_driver_put(), will hit BUG_ON(active_stack == NULL). patch 2 fix oops when do ls or cat in ocfs2 on hard readonly device. Because ocfs2_open_lock() will call

ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other
