ocfs2: should reclaim the inode if '__ocfs2_mknod_locked' returns an error
In ocfs2_mknod_locked if '__ocfs2_mknod_locke d' returns an error, we
should reclaim the inode successfully claimed above, otherwise, the
inode never be reused. The case is described below:
ocfs2_mknod
ocfs2_mknod_locked
ocfs2_claim_new_inode
Successfully claim the inode
__ocfs2_mknod_locked
ocfs2_journal_access_di
Failed because of -ENOMEM or other reasons, the inode
lockres has not been initialized yet.
iput(inode)
ocfs2_evict_inode
ocfs2_delete_inode
ocfs2_inode_lock
ocfs2_inode_lock_full_nested
__ocfs2_cluster_lock
Return -EINVAL because of the inode
lockres has not been initialized.
So the following operations are not performed
ocfs2_wipe_inode
ocfs2_remove_inode
ocfs2_free_dinode
ocfs2_free_suballoc_bits
