Subject: [PATCH 00/34] pnfs block layout driver based on v3.0-rc2
Date: Sun, 12 Jun 2011 19:43:45 -0400 [thread overview]
Message-ID: <cover.1307921137.git.rees@umich.edu> (raw)
For review only. This patch set adds the pnfs block layout driver to the
nfs client. It is roughly equivalent to the 88-patch set I sent earlier,
but is re-organized and based on v3.0-rc2.
There are several style problems, mostly white space and line
length problems, and I'll deal with those. I'm interested in comments on
the structure of the patch set, and of course the logic and functionality.
Date: Sun, 12 Jun 2011 19:43:45 -0400
Among these patches, the first 6 patches are generic layer change that is
needed for block layout driver.
Patch 7~32 are block driver code.
Patch 33 is the layout prefetch patch, which Benny agrees to take in for BAT
with the default value set to 0.
Patch 34 is the fix for layoutcommit vs. update_inode. Trond hasn't merged
it so I put it here as block driver need it to pass cthon hole file test.
Although the code is almost same as previous one, we did not have much time
fully testing it. It seems increased segment number (by reducing the layout
segment size) will sometimes cause client hang in cthon test. There may be
some bugs in either generic layer segment management or block driver extent
management (we already fixed some bugs in both parts). We will do more
investigation on it tomorrow.
