I'm sorry. My patch is error.
But I just want to get the git version when we use git as SCM. No matter what
.git directory where.
Thanks.

This patch fixed the error using 'git rev-parse --show-cdup' to check
that git is used as SCM to track the current directory. The return
value of this command is not null string when the .git directory is
not in kernel topdir.

Do you have any idea to fix such kind of issue?

I disagree.
If pfkey_error() is successful, the error will be reported in the AF_KEY
message that is broadcast, there is no reason for sendmsg to return an
send() syscall.

Maybe the only solution is to do some work on side effects just as you said.

allowed to place ahead of SACK chunk when bundling into one packet.
What do you think?
