2008-02-04Move count_partial before kmem_cache_shrinkChristoph Lameter1-13/+13
Move the counting function for objects in partial slabs so that it is placed before kmem_cache_shrink. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2008-02-04SLUB: Fix sysfs refcountingChristoph Lameter1-2/+13
If CONFIG_SYSFS is set then free the kmem_cache structure when sysfs tells us its okay. Otherwise there is the danger (as pointed out by Al Viro) that sysfs thinks the kobject still exists after kmem_cache_destroy() removed it.

2008-02-03fix writev regression: pan hanging unkillable and un-straceableNick Piggin1-2/+6
Frederik Himpe reported an unkillable and un-straceable pan process. Zero length iovecs can go into an infinite loop in writev, because the iovec iterator does not always advance over them. The sequence required to trigger this is not trivial. I think it requires that a zero-length iovec be followed by a non-zero-length iovec which causes a pagefault in the atomic usercopy. This causes the writev code to drop back into single-segment copy mode, which then tries to copy the 0 bytes of the zero-length iovec; a zero length copy looks like a failure though, so it loops. Put a test into iov_iter_advance to catch zero-length iovecs. We could just put the test in the fallback path, but I feel it is more robust to skip over zero-length iovecs throughout the code (iovec iterator may be used in filesystems too, so it should be robust).

Also, we add some comments stating which are the fields of the caps page in question in order to alleviate the cryptic pointer casting exercises as in e.g. idetape_get_mode_sense_results().
