This patch corrects some erroneous dentry handling in eCryptfs. If there is a problem creating the lower file, then there is nothing that the persistent lower file can do to really help us. This patch makes a vfs_create() failure in the lower filesystem always lead to an unconditional do_create failure in eCryptfs. Under certain sequences of operations, the eCryptfs dentry can remain in the dcache after an unlink. This patch calls d_drop() on the eCryptfs dentry to correct this. eCryptfs has no business calling d_delete() directly on a lower filesystem's dentry. This patch removes the call to d_delete() on the lower persistent file's dentry in ecryptfs_destroy_inode().
