This removes the remains of some debugging stuff which was never really enabled properly - it never reported memory leaks. Its not useful for anyone but me. A proper solution involves counting all requests in flight and all threads but we'll probably put that just into mm.

sget() is pessimistic and assumes it won't find a superblock - and as a result it always pre-allocates a new one before even searching for an existing entry. If it finds an existing one, it free's the extra one it just allocated. Especially with /proc usage it usually _does_ find an existing superblock, so this is all extra work. It should allocate a new one only if it couldn't find an old one (and re-search). The same way as iget() does it.

This one won't cause hangs, but can trip some WARNs.

Rather than not kfree'ing the UDF data in the case of a bad inode (which still _may_ have had the UDF data already allocated to it), make sure to initialize the pointer to NULL properly when we're done with it.

From: Arun Sharma <arun.sharma@intel.com> Based on some earlier discussion: http://marc.theaimsgroup.com/?t=106015010700002&r=1&w=2 here's a new patch that attempts to disable BLK_DEV_FD on platforms which don't support it. The patch also attempts to remove the duplication of the logic in compat_ioctl.h.

From: Roland McGrath <roland@redhat.com> gdb really needs some way to know the AT_SYSINFO_EHDR value for a process being debugged or for the dead process described by a core file. Without this value, it can't find the information necessary to show backtraces of threads waiting in system calls. There are any number of ways this information could be made available. Here is one solution that provides more debugging information in a clean and general fashion. I've added access to the AT_* values passed to a process for third parties to examine for debugging purposes. The same data passed on the stack at startup is made available in /proc/PID/auxv and is written in an NT_AUXV note in core dumps. (Both of these are consistent with what Solaris does using the same names.) Here are two different patches that implement the same thing differently. The first patch uses a ref-counted data structure to copy the aux vector and shares among forked mm's until they exec and get a new one. The second patch avoids the complexity of that data structure by simply expanding the mm_struct with space to hold a copy of the data. Both patches work correctly; I have examined the new /proc/PID/auxv file and core dumps. I hope you will consider including one of these patches, or at least some way of getting at this information from the debugger. I am certainly open to other suggestions on implementing this feature, and to suggestions on alternative interfaces for getting the AT_SYSINFO_EHDR value cleanly.

From: Rolf Eike Beer <eike-kernel@sf-tec.de> this patch makes some ints to unsigned ints. They are only used as loop counters and compared to unsigned ints. GCC 3.3 doesn't like this. They will never be negative anyway, so we could easily shut him up.

From: Stephen Smalley <sds@epoch.ncsc.mil> This patch changes the security_inode_permission hook to also take a nameidata parameter in addition to the existing inode and mask parameters. A nameidata is already passed (although sometimes NULL) to fs/namei.c:permission(), and the patch changes exec_permission_lite() to also take a nameidata parameter so that it can pass it along to the security hook. The patch includes corresponding changes to the SELinux module to use the nameidata information when it is available; this allows SELinux to include pathname information in audit messages when a nameidata structure was supplied.

From: Christoph Hellwig <hch@lst.de> It's the only abuse of proc_iops left (except the totally b0rked comx driver). The patch is from Al, I just forward-ported it from 2.4. Background: struct proc_dir_entry has a struct inode_operations *proc_iops member, it's from Linux's stoneage and used internally by procfs to assign either the link or directory inode ops. Unfortunately some drivers started to abuse it do do bad things like create on lookup (that's the comx thingy which relies on unexported symbols and thus is broken for modular builds since mid-2.3) or various ->permission tricks (all gone by now). After this patch is gone I have another one that kills proc_iops and just uses a normal conditional inside procfs to assign the right one directly.

From: Rusty Russell <rusty@rustcorp.com.au> Found this while converting netfilter modules to use the new parameters. Also fixes an out-by-one error in maximum elements you can put in array. The current "intarray" module params were never tested, and um, suck. Only one person uses them, and it looks painful. Since noone uses them, replace them with tested versions.

From: "Randy.Dunlap" <rddunlap@osdl.org>, Will Dyson <will_dyson@pobox.com>, me Add generic filesystem options parser (infrastructure) and use it to parse mount options in several filesystems (adfs, affs, autofs, autofs4, ext2, ext3, fat, hfs, hpfs, isofs, jfs, procfs, udf, and ufs). It saves between 128 and 512 bytes per filesystem.

From: "David S. Miller" <davem@redhat.com> This attempts to take care of 2 of the MM todos I had on my backlog: 1) Zap the stupid flush_cache_all() thing with more meaningful interfaces. 2) Resolve the ptrace user page access issues, first stage. The "first stage" mentioned for #2 is simply creating the user page accesor interfaces. The next stage needs to be mucking with get_user_pages() so that we can control when the flush_dcache_page() occurs. Then we: 1) For every platform where flush_dcache_page() is a non-nop add a call to the beginning of copy_{from,to}_user_page(). 2) Make access_process_vm() set the "no dcache flush" bit in it's call to get_user_pages(). The idea also was that we'd consolidate the write etc. boolean args passed to get_user_pages() into flag bits too. But at least with the below, we can delete that reminder FIXME comment from kernel/ptrace.c, the platforms have the necessary tools and just need to make use of it :) As a bonus I noticed that VMALLOC_VMADDR() did absolutely nothing. After all of this I only have 1 real TODO left, and that's dealing with the SMP TLB/pte invalidation stuff, very low priority until someone starts doing more work with sparc32/SMP in 2.6.x :)

Remove duplicated #defines

From: Andries.Brouwer@cwi.nl ext2 used a 32-bit field for dev_t, with possibly undefined storage following; thus, no action was required to go to 32-bit dev_t, but going to 64-bit dev_t required some subtlety: 0 was written in the first word and the 64 bits in the following two. Al truncated my 64-bit stuff to 32 bits but did not understand why there was this split, and wrote 0 followed by a single word. We should at least zero the word following to have well-defined storage later.

From: Oliver Xymoron <oxymoron@waste.org> I just noticed the ikconfig stuff made it into mainline via -mm. I also just noticed that it's based in part on a patch I posted almost 5 years ago: http://groups.google.com/groups?q=oliver+xymoron+config.gz&hl=en&lr=&ie=UTF-8&selm=fa.j8fsl5v.g08fjo%40ifi.uio.no&rnum=2 Sadly, after wandering aimlessly in the desert of unloved patches all those years, all attribution got lost. This adds a copyright + license to scripts/bin2c.c, which hasn't aged a day.

From: Herbert Xu <herbert@gondor.apana.org.au> Currently com20020 and com20020_cs both call request_region on the same block of ports leading to a conflict. This patch resolves this by moving request_region out of the generic driver and into the isa/pci/cs drivers.

This fixes the qla1280 driver to not try to release an unlocked spinlock at boot time - as well as a couple of other minor mods. I also changed the MMIO option to be dependant on X86_VISWS as it's really a chipset problem and not something each and every driver should be asking for. Getting a global CONFIG_MMIO_IS_BROKEN option would probable be a win here.

This fixes (again...) CPU frequency calibration on some platforms with the Cypress chip. That is, at some point CLOCK_TICK_RATE has been changed to represent RTC reference clock instead of PIC one. Which makes calibrate_cc_with_pic() produce utterly bogus results.

Here is a very small set of fixes for Linux/axp, with a new one for "sched_clock" just introduced. Note that all but the arch/alpha/mm/init.c are required for a clean build, since warnings->errors is still on. The arch/alpha/mm/init.c stuff is from Jeff for MARVEL, and MUST be there for any machines running the latest firmware...
