We need to keep track of these skbs so that we can\n free them, but by tracking them, we can also easily re-use them.\n\n The new patch was a response to the behavior of certain network\n drivers. We cannot reuse an skb that the network driver still has\n in its transmit ring. Network drivers can defer transmit ring\n cleanup and then use the state in the skb to determine how many data\n segments to clean up in its transmit ring. The tg3 driver is one\n driver that behaves in this way.\n\n When the network driver defers cleanup of its transmit ring, the aoe\n driver can find itself in a situation where it would like to send an\n AoE command, and the AoE target is ready for more work, but the\n network driver still has all of the pre-allocated skbs. In that\n case, the new patch just calls alloc_skb, as you\u0027d expect.\n\n We don\u0027t want to get carried away, though. We try not to do\n excessive allocation in the write path, so we cap the number of skbs\n we dynamically allocate.\n\n Probably calling it a \"dynamic pool\" is misleading. We were already\n trying to use a small fixed-size set of pre-allocated skbs before\n this patch, and this patch just provides a little headroom (with a\n ceiling, though) to accomodate network drivers that hang onto skbs,\n by allocating when needed. The d-\u003eskbpool_hd list of allocated skbs\n is necessary so that we can free them later.\n\n We didn\u0027t notice the need for this headroom until AoE targets got\n fast enough.\n\nAlternatives\n\n If the network layer never did a put_page on the pages in the bio\u0027s\n we get from the block layer, then it would be possible for us to\n hand skbs to the network layer and forget about them, allowing the\n network layer to free skbs itself (and thereby calling our own\n skb-\u003edestructor callback function if we needed that). In that case\n we could get rid of the pre-allocated skbs and also the\n d-\u003eskbpool_hd, instead just calling alloc_skb every time we wanted\n to transmit a packet. The slab allocator would effectively maintain\n the list of skbs.\n\n Besides a loss of CPU cache locality, the main concern with that\n approach the danger that it would increase the likelihood of\n deadlock when VM is trying to free pages by writing dirty data from\n the page cache through the aoe driver out to persistent storage on\n an AoE device. Right now we have a situation where we have\n pre-allocation that corresponds to how much we use, which seems\n ideal.\n\n Of course, there\u0027s still the separate issue of receiving the packets\n that tell us that a write has successfully completed on the AoE\n target. When memory is low and VM is using AoE to flush dirty data\n to free up pages, it would be perfect if there were a way for us to\n register a fast callback that could recognize write command\n completion responses. But I don\u0027t think the current problems with\n the receive side of the situation are a justification for\n exacerbating the problem on the transmit side.\n\nSigned-off-by: Ed L.

Such a device might have more\nthan one network interface, and it might be reachable by more than one local\nnetwork interface. This patch tracks the available network paths available to\neach AoE device, allowing them to be used more efficiently.\n\nAndrew Morton asked about the call to msleep_interruptible in the revalidate\nfunction. Yes, if a signal is pending, then msleep_interruptible will not\nreturn 0. That means we will not loop but will call aoenet_xmit with a NULL\nskb, which is a noop. If the system is too low on memory or the aoe driver is\ntoo low on frames, then the user can hit control-C to interrupt the attempt to\ndo a revalidate. I have added a comment to the code summarizing that.\n\nAndrew Morton asked whether the allocation performed inside addtgt could use a\nmore relaxed allocation like GFP_KERNEL, but addtgt is called when the aoedev\nlock has been locked with spin_lock_irqsave. It would be nice to allocate the\nmemory under fewer restrictions, but targets are only added when the device is\nbeing discovered, and if the target can\u0027t be added right now, we can try again\nin a minute when then next AoE config query broadcast goes out.\n\nAndrew Morton pointed out that the \"too many targets\" message could be printed\nfor failing GFP_ATOMIC allocations. The last patch in this series makes the\nmessages more specific.\n\nSigned-off-by: Ed L.

And in general it is completely\nwrong for a block device driver to do this.\n\nThe new one is more like a regular block device driver. It has no idea about\nvm/vfs stuff.

This means that this bit of arch\n code will be stored in the appropriate A.OUT binfmt module rather than\n the core kernel.\n\n (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it\u0027s not\n needed) and FRV.\n\nThis patch depends on the previous patch to move STACK_TOP[_MAX] out of\nasm/a.out.h and into asm/processor.h as they\u0027re required whether or not A.OUT\nformat is available.\n\n[jdike@addtoit.com: uml: re-remove accidentally restored code]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b0b933c08bd5fd053bbba8ba6387f543be03d49f", "tree": "c3c6d2e44d2104231daa31f684b9e7fcdc3b7896", "parents": [ "922a70d327bd4b11342c2afd08e20d35f52064c3" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Feb 08 04:19:27 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:30 2008 -0800" }, "message": "aout: mark arches that support A.OUT format\n\nMark arches that support A.OUT format by including the following in their\nmaster Kconfig files:\n\n\tconfig ARCH_SUPPORTS_AOUT\n\t\tdef_bool y\n\nThis should also be set if the arch provides compatibility A.OUT support for\nan older arch, for instance x86_64 for i386 or sparc64 for sparc.\n\nI\u0027ve guessed at which arches don\u0027t, based on comments in the code, however I\u0027m\nsure that some of the ones I\u0027ve marked as \u0027yes\u0027 actually should be \u0027no\u0027.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "922a70d327bd4b11342c2afd08e20d35f52064c3", "tree": "aff7e43fa600363128c15c4b9a1ceba3869aac15", "parents": [ "3eb056764dd806bbe84eb604e45e7470feeaafd8" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Feb 08 04:19:26 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:29 2008 -0800" }, "message": "aout: move STACK_TOP[_MAX] to asm/processor.h\n\nMove STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they\u0027re\nrequired whether or not A.OUT format is available.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3eb056764dd806bbe84eb604e45e7470feeaafd8", "tree": "97a8fe2123d2c9df2bcb48052ac33d445a00f64c", "parents": [ "cf4fc6cb76e50b01666e28a9f4b2e6fbcbb96d5f" ], "author": { "name": "Li Zefan", "email": "lizf@cn.fujitsu.com", "time": "Fri Feb 08 04:19:25 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:29 2008 -0800" }, "message": "time: fix typo in comments\n\nFix typo in comments.\n\nBTW: I have to fix coding style in arch/ia64/kernel/time.c also, otherwise\ncheckpatch.pl will be complaining.\n\nSigned-off-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "cf4fc6cb76e50b01666e28a9f4b2e6fbcbb96d5f", "tree": "ac1e027b7e759822014bd3a72ababd1fa1052198", "parents": [ "0b858e6ff9a38b987a83d22e6f2a2f621c80608d" ], "author": { "name": "Li Zefan", "email": "lizf@cn.fujitsu.com", "time": "Fri Feb 08 04:19:24 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:29 2008 -0800" }, "message": "timekeeping: rename timekeeping_is_continuous to timekeeping_valid_for_hres\n\nFunction timekeeping_is_continuous() no longer checks flag\nCLOCK_IS_CONTINUOUS, and it checks CLOCK_SOURCE_VALID_FOR_HRES now.

So, do_wait(..., WNOHANG) returns 0, this doesn\u0027t\nmatch the behaviour above. Without WNOHANG do_wait() blocks only to\nreturn the error later, when the child will be untraced. Inho, really\nstrange.\n\nI think eligible_child() should return the error only if the child\u0027s pid\nwas requested explicitly, otherwise we should silently ignore the tasks\nwhich were nacked by security_task_wait().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Eric Paris \u003ceparis@redhat.com\u003e\nCc: James Morris \u003cjmorris@namei.org\u003e\nCc: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "96fabbf55ae79826f2e8a86f4066d7e8834315ae", "tree": "e4b3259a744a1e0c8fa477e3dfba02e4ea1993c8", "parents": [ "1bad95c3bee183719e15eebffef66afc3fb3f8b0" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Fri Feb 08 04:19:04 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Feb 08 09:22:26 2008 -0800" }, "message": "do_wait: cleanup delay_group_leader() usage\n\neligible_child() \u003d\u003d 2 means delay_group_leader().
