Hi,
I got a unix socket soft lockup issue in rhel 6.7(kernel 2.6.32+) ppc64.
And found that commit
60bc851 could fix this bug by git bisect. Please got the details at
https://bugzilla.redhat.com/show_bug.cgi?id=1238062
commit 60bc851ae59bfe99be6ee89d6bc50008c85ec75d

af_unix: fix a fatal race with bit fields
What's more I found this patch hadn't been included into kernel stable
tree from 2.6.32 to 3.8.
If this patch was not included, in powerpc/sparc, kernel will report
soft lockup when doing
unix socket recv/sendmsg in some cases.
B.R.
Justin
