- Fixed message concerning stats & range data to include '.dat'

[PATCH] blktrace.c should ignore SIGPIPE

After sending a SIGINT to a "blktrace .. | blkparse .. " pipeline,
occasionally I would not be able to run blktrace again. On my next run
of the same pipeline I would get the following error:

cs411vm:/usr/src/bt# ./blktrace -d /dev/sdb -o - | ./blkparse -i -
BLKTRACESETUP: No such file or directory
Failed to start trace on /dev/sdb

After rebooting, I could reproduce this by starting the pipeline, and
kicking off a big write and sending a SIGINT to blktrace. The following
is what I used for a write:

while [ 1 ]
do
    dd if=/dev/zero of=/test/write bs=1M
done

It seemed like blktrace was not handling signals correctly, so I
strace'd the process to see what was happening.

Sure enough:

--- SIGINT (Interrupt) @ 0 (0) ---
ioctl(3, 0x1275, 0xb7fa6000)            = 0
sigreturn()                             = ? (mask now [])
write(1, "O\0\0\0\20\0\200\0\0\0\0\0\0\0\0\0\7taeN3\1\0\257R\260"...,
4096) = -1 EPIPE (Broken pipe)
--- SIGPIPE (Broken pipe) @ 0 (0) ---
+++ killed by SIGPIPE +++

Any idea what clean-up is not happening? I tried to figure it out, but
my only work-around was a reboot.

My patch against 2.6.17-rc3 just tells blktrace to ignore SIGPIPE.
Nothing crazy. :) blktrace already does enough error checking elsewhere
to handle a bad write.

On a completely unrelated note, the write_data function calls fwrite,
which will not return -1 on error. Instead you'll need to use ferror to
check if there was a problem. I'm not sure if this is a cause of any
bugs, but it seemed worth mentioning.

Furthermore, I updated the URLs in the documentation to point at a valid
git repo.

[PATCH] blktrace: fix sendfile problem with > buf_size xmits

Basically, it add buf_size, buf_nr and page_size to the net header and
this info is put into each tip, for easy access in mmap_subbuf().  The
global buf_size, etc is still used by clients, since the global value is
all they need (for clients, the tip is filled in with the global values
anyway, so that mmap_subbuf() can use them, maybe the tip->buf_size
should be used everywhere instead for consistency and only use the
global values for initial args.  Also, each tip doesn't really need to
have these values, they could be stored in tip->device but I thought it
would be easier and quicker to access tip->buf_size rather than
tip->device->buf_size).  Actually, this data only needs to be sent once
per trace, but since there's no header covering the entire trace, sends
it each time.  Could be an optimization to make later...

I've tested it using sendfile over the network with different buffer
sizes, and with normal non-sendfile network and non-network tracing
straight to disk, and haven't seen any problems.  Each test generated a
little over 1Gb of trace data in a little under 2 minutes, just under 23
million events after parsing, so it looks to me like it's doing the job
at this point...
