/*

 * Scan from the current position of the sync pointer to find the entry that

 * corresponds to the given ppa. This is necessary since write requests can be

 * completed out of order. The assumption is that the ppa is close to the sync

 * pointer thus the search will not take long.

 *

 * The caller of this function must guarantee that the sync pointer will no

 * reach the entry while it is using the metadata associated with it. With this

 * assumption in mind, there is no need to take the sync lock.
