Revision 3f380998aeb51b99d5d22cadb41162e1e9db70d2 authored by Kautuk Consul on 01 November 2011, 00:09:11 UTC, committed by Linus Torvalds on 01 November 2011, 00:30:49 UTC
write_scan_unevictable_node() checks the value req returned by strict_strtoul() and returns 1 if req is 0. However, when strict_strtoul() returns 0, it means successful conversion of buf to unsigned long. Due to this, the function was not proceeding to scan the zones for unevictable pages even though we write a valid value to the scan_unevictable_pages sys file. Change this check slightly to check for invalid value in buf as well as 0 value stored in res after successful conversion via strict_strtoul. In both cases, we do not perform the scanning of this node's zones.
