SYNOPSIS¶
int filemap_fdatawait_range(struct address_space * mapping, loff_t start_byte, loff_t end_byte);
ARGUMENTS¶
struct address_space * mapping
address space structure to wait for
loff_t start_byte
offset in bytes where the range starts
loff_t end_byte

DESCRIPTION¶
Walk the list of under-writeback pages of the given address space in the given range and wait for all of them. Check error status of the address space and return it.
