Revision c85e9a97c4102ce2e83112da850d838cfab5ab13 authored by Wu Fengguang on 02 February 2010, 21:44:06 UTC, committed by Linus Torvalds on 03 February 2010, 02:11:22 UTC
write_kmem() used to assume vwrite() always return the full buffer length. However now vwrite() could return 0 to indicate memory hole. This creates a bug that "buf" is not advanced accordingly. Fix it to simply ignore the return value, hence the memory hole.
