try_to_release_page — release old fs-specific metadata on a page


int try_to_release_page (struct page * page,
 gfp_t gfp_mask);


struct page * page

the page which the kernel is trying to free

gfp_t gfp_mask

memory allocation flags (and I/O mode)


The address_space is to try to release any data against the page (presumably at page->private). If the release was successful, return `1'. Otherwise return zero.

This may also be called if PG_fscache is set on a page, indicating that the page is known to the local caching routines.

The gfp_mask argument specifies whether I/O may be performed to release this page (__GFP_IO), and whether the call may block (__GFP_RECLAIM & __GFP_FS).
