* [PATCH] Introduce vfs_listxattrBill Nottingham2006-10-09
| | | | | | | | | | | | | | | | | | | | | This patch moves code out of fs/xattr.c:listxattr into a new function - vfs_listxattr. The code for vfs_listxattr was originally submitted by Bill Nottingham <notting@redhat.com> to Unionfs. Sorry about that. The reason for this submission is to make the listxattr code in fs/xattr.c a little cleaner (as well as to clean up some code in Unionfs.) Currently, Unionfs has vfs_listxattr defined in its code. I think that's very ugly, and I'd like to see it (re)moved. The logical place to put it, is along side of all the other vfs_*xattr functions. Overall, I think this patch is benefitial for both kernel.org kernel and Unionfs.

* [PATCH] knfsd: tidy up up meaning of 'buffer size' in nfsd/sunrpcNeilBrown2006-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | There is some confusion about the meaning of 'bufsz' for a sunrpc server. In some cases it is the largest message that can be sent or received. In other cases it is the largest 'payload' that can be included in a NFS message. In either case, it is not possible for both the request and the reply to be this large. One of the request or reply may only be one page long, which fits nicely with NFS. So we remove 'bufsz' and replace it with two numbers: 'max_payload' and 'max_mesg'. Max_payload is the size that the server requests. It is used by the server to check the max size allowed on a particular connection: depending on the protocol a lower limit might be used. max_mesg is the largest single message that can be sent or received. It is calculated as the max_payload, rounded up to a multiple of PAGE_SIZE, and with PAGE_SIZE added to overhead. Only one of the request and reply may be this size. The other must be at most one page. Cc: Greg Banks <gnb@sgi.com> Cc: "J.

| * IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In many places GFS2 was calling the endian conversion routines for an inode even when only a single field, or a few fields might have changed. As a result we were copying lots of data needlessly. This patch replaces those calls with conversion of just the required fields in each case. This should be faster and easier to understand.

(It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

Updated the directory code to use the new & improved version of gfs2_meta_ra() which now returns the first block that was being read. Previously it was releasing it requiring following code to grab the block again at each point it was called. Also turned off readahead on directory lookups since we are reading a hash table, and therefore reading the entries in order is very unlikely. Readahead is still used for all other calls to the directory reading function (e.g. when growing the hash table). Removed the DIO_START constant. Everywhere this was used, it was used to unconditionally start i/o aside from a couple of places, so I've removed it and made the couple of exceptions to this rule into separate functions. Also hunted through the other DIO flags and removed them as arguments from functions which were always called with the same combination of arguments. Updated gfs2_meta_indirect_buffer to be a bit more efficient and hopefully also be a bit easier to read. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
