FILEMAP_FDATAWAIT_RA(9)             Memory Management in Linux            FILEMAP_FDATAWAIT_RA(9)



NAME
       filemap_fdatawait_range - wait for writeback to complete

SYNOPSIS
       int filemap_fdatawait_range(struct address_space * mapping, loff_t start_byte,
                                   loff_t end_byte);

ARGUMENTS
       mapping
           address space structure to wait for

       start_byte
           offset in bytes where the range starts

       end_byte
           offset in bytes where the range ends (inclusive)

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.

       Since the error status of the address space is cleared by this function, callers are
       responsible for checking the return value and handling and/or reporting the error.
