This happens when __logfs_create() tries to write a new inode to the disk which is full. __logfs_create() associates the transaction pointer with inode. During the logfs_write_inode() function call chain this transaction pointer is moved from inode to page->private using function move_inode_to_page (do_write_inode() -> inode_to_page() -> move_inode_to_page) When the write inode fails, the transaction is aborted and iput is called on the failed inode. During delete_inode the same transaction pointer associated with the page is getting used. Thus causing kernel BUG. The patch checks for error in write_inode() and restores the page->private to NULL.
