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 Signed-off-by: Alex Chen <alex.chen@huawei.com> Reviewed-by: Joseph Qi <joseph.qi@huawei.com> Cc: Mark Fasheh <mfasheh@suse.de> Cc: Joel Becker <jlbec@evilplan.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
