sync_page_range(9)
NAME
sync_page_range - write and wait on all pages in the passed range
SYNOPSIS
int sync_page_range(struct inode * inode,
struct address_space * mapping, loff_t pos,
loff_t count);
ARGUMENTS
- inode
- target inode
- mapping
- target address_space
- pos
- beginning offset in pages to write
- count
- number of bytes to write
DESCRIPTION
Write and wait upon all the pages in the passed range. This is a "data
integrity" operation. It waits upon in-flight writeout before starting
and waiting upon new writeout. If there was an IO error, return it.
We need to re-take i_mutex during the generic_osync_inode list walk
because it is otherwise livelockable.
