The bug (http://bugzilla.kernel.org/show_bug.cgi?id=12913) is not rare with the right workload at all. I can easily make it happen on smp machines, when multiple processes are writing to the same NFS mounted file system. AFAICT this needs to be back ported to 27 stable and 29 stable as well. Nick, are there 27 based patches already available someplace? Obviously, I have verified these patches + Trond's patch -- http://lkml.org/lkml/2009/4/25/64 fixes the issue with 2.6.30-rc3 Thanks, Kiran -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
