NAME
replace_page_cache_page - replace a pagecache page with a new one
SYNOPSIS
int replace_page_cache_page(struct page * old, struct page * new, gfp_t gfp_mask);
ARGUMENTS
old page to be replaced new page to replace with gfp_mask allocation mode
DESCRIPTION
This function replaces a page in the pagecache with a new one. On success it acquires the pagecache reference for the new page and drops it for the old page. Both the old and new pages must be locked. This function does not add the new page to the LRU, the caller must do that. The remove + add is atomic. The only way this function can fail is memory allocation failure.
