Revision 475f9aa6aa538befcbd0fa95bdebada600f247cd authored by Vitaly Mayatskikh on 11 May 2010, 21:06:51 UTC, committed by Linus Torvalds on 12 May 2010, 00:33:42 UTC
Two "echo 0 > /sys/kernel/kexec_crash_size" OOPSes kernel. Also content of this file is invalid after first shrink to zero: it shows 1 instead of 0. This scenario is unlikely to happen often (root privs, valid crashkernel= in cmdline, dump-capture kernel not loaded), I hit it only by chance. This patch fixes it.
