      [PATCH] call_usermodehelper retval fix · be907e49
      Andrew Morton authored
      The reworked firmware loader in the DVB patches needs the fix to the
      call_usermodehelper() return value. 
      
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      MODULE_ALIAS_BLOCK() and MODULE_ALIAS_CHAR() define aliases of form
      "XXX-<major>-<minor>", so we should probe for modules using this form.
      Unfortunately in 2.4, block aliases were "XXX-<major>" and char aliases
      were of both forms.
      
      Ideally, all modules would now be using MODULE_ALIAS() macros to define
      their aliases, and the old configuration files wouldn't matter as much. 
      Unfortunately, this hasn't happened, so we make request_module() return the
      exit status of modprobe, and then do fallback when probing for char and
      block devices.
      
      (Kudos to Chris Wright, I stole his kernel_thread flags).

      Andrew Morton authored
      From: David Hinds <dhinds@sonic.net>
      
      This fixes interrupt allocation for 16-bit PCMCIA cards, so that on systems
      supporting ISA bus interrupts, if all ISA interrupts are unavailable, we'll
      fall back on sharing the bridge PCI interrupt.

      From: David Hinds <dhinds@sonic.net>
      
      I have not been actively maintaining PCMCIA for 2.6; I tried asking the
      more active developers to see if someone would step into the job but they
      were not willing to do so at this time.  I'll still submit patches from
      time to time.
      
      (David has a ./CREDITS entry, of course).
      
      We should really put in Russell King here, but I'll let him do that
      himself.

      [PATCH] PPC32: Fix the mkprep util to work correctly on Solaris 8 · 856b46ae

            Peter Wahl <PeterWahl@web.de>
      
      PPC32: Fix the mkprep util to work correctly on Solaris 8.
      
      - There is a very odd problem with the alignment of dword_t values
        which causes this program to not work correctly when compiled on
        Solaris 8.  The workaround is not use a pointer and to memcpy the
        values instead.

      [PATCH] readahead: multiple performance fixes · 2fbe6496
      Andrew Morton authored
      From: Ram Pai <linuxram@us.ibm.com>
      
      I have enclosed a patch that fixes a bunch of performance bugs in the
      readahead code.
      
      Below is a brief summary of the problems noticed and the proposed fixes
      with some results:
         
       Problem 1:  Readahead code closes the readahead window and goes into
       slowread path, if a file is accessed the first time at an offset
       notequal to zero.  In the case of databases(especially in db2), a file
       may not be accessed at offset 0 the first time though the i/o's are
       sequential.
      
       Fix to Problem 1:
                min = get_min_readahead(ra);
               orig_next_size = ra-next_size;
      
       -       if (ra-next_size == 0 && offset == 0) {
       +       if (ra-next_size == 0) {
      
      ------------------------------------------------------------------------
      
       ------------------------------------------------------------------------
       Problem 2: After fixing Problem, the readahead window still does not
       open up the first time, if all the pages requested are already in the
       page cache. This time the window closes because of pagecache hits
       instead of misses. To fix this we put in these changes.
      
       -               check_ra_success(ra, ra-size, actual, orig_next_size);
       +               if(!first_access) {
       +                       check_ra_success(ra, ra-size, actual, orig_next_size);
       +               }
      
       ------------------------------------------------------------------------
      
       ------------------------------------------------------------------------
       Problem 3: In the case of large random reads, the readahead window is
       read in, the moment there is a hit in the active window. And it turns
       out that in most of the cases the readahead window gets scrapped,
       because the next large random read does not even touch any of the pages
       in that readahead window. We fixed this by introducing lazy readahead.
       Basically we wait till the last page in the active window gets a hit.
       And once the last page is hit, the readahead window is then read in.
       This fix gave a tremendous boost in the performance.
       To fix this the changes we put in were:
      
                       /*
                        * This read request is within the current window.  It is time
                        * to submit I/O for the ahead window while the application is
                        * crunching through the current window.
                        */
       -               if (ra-ahead_start == 0) {
       +               if (ra-ahead_start == 0 && offset == (ra-start + ra-size -1)) {
      
       ------------------------------------------------------------------------
      
       ------------------------------------------------------------------------
       Problem 4:
             If the request page does not fall in the active window and is not
      the  first page of the read ahead window, we scrap both the active
      window and the readahaed window and read in the active window. But it
      turns out that we read in a lot of pages in the active window based on
      the size of the 'projected readahead window size' (the next_size
      variable). And we end up using part of the active window and waste the
      remaining. We put  in a fix where we read in just as many pages in the
      active window based on the number of pages used in the recent past.
       Again this gave us another big boost in performance and ended up
      beating the performance of aio patch on a DSS workload.
      
       The fix to this is:
                        * ahead window and get some I/O underway for the new
                        * current window.
                        */
       +               if (!first_access && preoffset = ra-start &&
       +                               preoffset < (ra-start + ra-size)) {
       +                       ra-size = preoffset - ra-start + 2;
       +               } else {
       +                       ra-size = ra-next_size;
      
       ------------------------------------------------------------------------
      
       ------------------------------------------------------------------------
       Problem 5:
       With all the above fixes there is very low chance that the readahead
       window shall close.  But however if it does, we found that the slow
       read  path is really slow.  Any loss of sequentiality in the slow read
       path is penalized heavily by closing the window back to zero. So we
       fixed this  by decreasing the window size by one anytime we loose
       sequentiality and  increasing in by 1 if we didn't.
      
                       if (offset != ra-prev_page + 1) {
       -                       ra-size = 0;            /* Not sequential */
       +                       ra-size = ra-size?ra-size-1:0; /*Notsequential */
      
       ------------------------------------------------------------------------
      
      With the above set of fixes we got about 28% improvement in DSS workload
      which is about 5% more than what we got with the suparna's aio patch.
      
      This patch compared equivalent to suparna's aio patch with aio-stress
      run.
      
      It fared better than aio patch for large random io.
      
      We are yet to run a bunch of other benchmarks to evaluate this patch.
      We would like to get your inputs on this patch and any suggestions you
      may have to improve it. I have enclosed a patch with all these changes
      along with some changes to the comments that reflect the new behaviour.
      NOTE: the above patch reverts suparna's aio patch.

      [PATCH] Fix 2.6.0's broken documentation references · 56d7e6f4
      Andrew Morton authored
      From: Hans Ulrich Niedermann <linux-kernel@n-dimensional.de>
      
      I've noted that 2.6.0 contains broken references to documentation.
      
      I got sufficiently annoyed chasing doc files in the wrong place
      that I wrote a script to check the references to documentation
      files.
      
      Some documentation files have moved (e.g.  Documentation/modules.txt to
      Documentation/kbuild/modules.txt).  I adapted the references with a script.

      [PATCH] shrink_slab acounts for seeks incorrectly · c3f46561
      Andrew Morton authored
      wli points out that shrink_slab inverts the sense of shrinker->seeks: those
      caches which require more seeks to reestablish an object are shrunk harder.
      That's wrong - they should be shrunk less.
      
      So fix that up, but scaling the result so that the patch is actually a no-op
      at this time, because all caches use DEFAULT_SEEKS (2).
