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

number of bytes to write

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.
