X-Git-Tag: v3.14-rc1~171^2~15^2~24 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=100b907350c87aa1f3b5dbd95bac3ad5aad3e108;p=pandora-kernel.git perf kvm: Introduce option -v for perf kvm command. As there is no -v option for perf kvm, the all debug message for perf kvm will nerver be printed out to user. Example: # perf kvm --guestmount /tmp/guestmount/ record -a Not enough memory for reading perf file header It is confusing message for newbies such as me. With this patch applied, we can use -v option to get the detail. Example: # perf kvm --guestmount /tmp/guestmount/ record -a -v Can't access file /tmp/guestmount//15069/proc/kallsyms Not enough memory for reading perf file header Signed-off-by: Dongsheng Yang Cc: David Ahern Link: http://lkml.kernel.org/r/1386609311-23889-1-git-send-email-yangds.fnst@cn.fujitsu.com Signed-off-by: Arnaldo Carvalho de Melo --- Reading git-diff-tree failed
