Name:scrypt_free_bounce_page() - free a ciphertext bounce page* Free a bounce page that was allocated by fscrypt_encrypt_pagecache_blocks(),* or by fscrypt_alloc_bounce_page() directly.

Type:void

TypeParameterName
struct page *bounce_page
65  If Not bounce_page Then Return
67  set_page_private(bounce_page, (unsignedlong)NULL)
68  Private page markings that may be used by the filesystem that owns the page* for its own purposes.* - PG_private and PG_private_2 cause releasepage() and co to be invoked
69  mempool_free - return an element to the pool.*@element: pool element pointer.*@pool: pointer to the memory pool which was allocated via* mempool_create().* this function only sleeps if the free_fn() function sleeps.
