Subject: Re: + proc-dont-lock-task_structs-indefinitely-cpuset-fix-2.patch added to -mm tree
Date: Tue, 28 Feb 2006 20:10:40 -0800	[thread overview]
Message-ID: <20060228201040.34a1e8f5.pj@sgi.com> (raw)
In-Reply-To: <20060228194525.0faebaaa.pj@sgi.com>

With these three patches:
    proc-dont-lock-task_structs-indefinitely.patch
    proc-dont-lock-task_structs-indefinitely-git-nfs-fix.patch
    proc-dont-lock-task_structs-indefinitely-cpuset-fix.patch

the command:

    /bin/fuser -n tcp 5553

kills my kernel very quickly.  This latest time it died with
the swap command failure I mentioned before.  And this command
shows the permission problem (2) that I reported to Eric.

The full output, from command entry to death, is as
follows.  The second '#', near the end, is my shell
prompt returning to me, microseconds before death.

# /bin/fuser -n tcp 5553
