TRY_TO_RELEASE_PAGE(9) Memory Management in Linux TRY_TO_RELEASE_PAGE(9)NAMEtry_to_release_page - release old fs-specific metadata on a page
SYNOPSIS
int try_to_release_page(struct page * page, gfp_t gfp_mask);
ARGUMENTS
page
the page which the kernel is trying to free
gfp_mask
memory allocation flags (and I/O mode)
DESCRIPTION
The address_space is to try to release any data against the page
(presumably at page->private). If the release was successful, return
`1ยด. 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_WAIT &
__GFP_FS).
