NAME

read_cache_page_gfp - read into page cache, using specified page allocation flags.  

SYNOPSIS

struct page * read_cache_page_gfp(struct address_space * mapping, pgoff_t index, gfp_t gfp);
 

ARGUMENTS

mapping

the page's address_space

index

the page index

gfp

the page allocator flags to use if allocating
 

DESCRIPTION

This is the same as lqread_mapping_page(mapping, index, NULL)rq, but with any new page allocations done using the specified allocation flags. Note that the Radix tree operations will still use GFP_KERNEL, so you can't expect to do this atomically or anything like that - but you can pass in other page requirements.

If the page does not get brought uptodate, return -EIO.
