NAME
sync_page_range - write and wait on all pages in the passed rangeSYNOPSIS
- 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.
