Name
sync_page_range_nolock —
write & wait on all pages in the passed range without locking
Synopsis
int sync_page_range_nolock ( | 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

Note
Holding i_mutex across sync_page_range_nolock is not a good idea
as it forces O_SYNC writers to different parts of the same file
to be serialised right until io completion.
