NAME
invalidate_mmap_range - invalidate the portion of all mmaps
SYNOPSIS
"SYNOPSIS"
void invalidate_mmap_range (struct address_space * mapping, loff_t const holebegin, loff_t const holelen);
ARGUMENTS
- mapping
-
-- undescribed --
- holebegin
-
byte in first page to invalidate, relative to the start of
the underlying file. This will be rounded down to a PAGE_SIZE
boundary. Note that this is different from vmtruncate, which
must keep the partial page. In contrast, we must get rid of
partial pages.
- holelen
-
size of prospective hole in bytes. This will be rounded
up to a PAGE_SIZE boundary. A holelen of zero truncates to the
end of the file.
DESCRIPTION
in the specified address_space corresponding to the specified
page range in the underlying file.
