ignore return value from readahead()
do_readahead() requires a_ops->readpage to be != NULL: 568 static ssize_t 569 do_readahead(struct address_space *mapping, struct file *filp, 570 pgoff_t index, unsigned long nr) 571 { 572 if (!mapping || !mapping->a_ops || !mapping->a_ops->readpage) 573 return -EINVAL; 574 575 force_page_cache_readahead(mapping, filp, index, nr); 576 return 0; 577 } but following commit removed readpage from hugetlbfs: commit f2deae9d4e70793568ef9e85d227abb7bef5b622 Author: Mel Gorman <mel@csn.ul.ie> Date: Wed May 13 15:56:10 2009 +0100 Remove implementation of readpage from the hugetlbfs_aops So this is going to always return EINVAL on patched kernels. Ignore return value, regardless of readahead() outcome testcase will still check if reservation counter gets corrupted.
