commit 142578a5061ad2ce4fe789c1524e2eb5cb102b0e Author: Penny Zheng <Penny.Zheng@xxxxxxx> AuthorDate: Tue Sep 6 15:39:18 2022 +0800 Commit: Julien Grall <jgrall@xxxxxxxxxx> CommitDate: Tue Sep 6 17:53:35 2022 +0100 xen: rename free_staticmem_pages to unprepare_staticmem_pages The name of free_staticmem_pages is inappropriate, considering it is the opposite of function prepare_staticmem_pages. Rename free_staticmem_pages to unprepare_staticmem_pages.
