SYNOPSIS

9       int filemap_fdatawait_range(struct address_space * mapping,
10                                   loff_t start_byte, loff_t end_byte);
11

ARGUMENTS

13       mapping
14           address space structure to wait for
15
16       start_byte
17           offset in bytes where the range starts
18
19       end_byte
20           offset in bytes where the range ends (inclusive)

DESCRIPTION

23       Walk the list of under-writeback pages of the given address space in
24       the given range and wait for all of them. Check error status of the
25       address space and return it.
26
27       Since the error status of the address space is cleared by this
28       function, callers are responsible for checking the return value and
29       handling and/or reporting the error.
