This patch (as761) makes it return -ENOMEM when the per-cpu data\nallocation fails.\n\nThe patch also makes srcu_init_notifier_head() report a BUG if a notifier\nhead can\u0027t be initialized. Perhaps it should return -ENOMEM instead, but\nin the most likely cases where this might occur I don\u0027t think any recovery\nis possible.

SRCU is as follows:\n\no\tEach use of SRCU creates its own srcu_struct, and each\n\tsrcu_struct has its own set of grace periods. This is\n\tcritical, as it prevents one subsystem with a blocking\n\treader from holding up SRCU grace periods for other\n\tsubsystems.\n\no\tThe SRCU primitives (srcu_read_lock(), srcu_read_unlock(),\n\tand synchronize_srcu()) all take a pointer to a srcu_struct.\n\no\tThe SRCU primitives must be called from process context.\n\no\tsrcu_read_lock() returns an int that must be passed to\n\tthe matching srcu_read_unlock(). Realtime RCU avoids the\n\tneed for this by storing the state in the task struct,\n\tbut SRCU needs to allow a given code path to pass through\n\tmultiple SRCU domains -- storing state in the task struct\n\twould therefore require either arbitrary space in the\n\ttask struct or arbitrary limits on SRCU nesting.

First it allocates a\nplatform dependent routing value for an interrupt the ``vector\u0027\u0027 and then it\nfigures out from the vector which irq you are on.\n\nThis msi backwards allocator suffers from two basic problems. The allocator\nsuffers because it is trying to do something that is architecture specific in\na generic way making it brittle, inflexible, and tied to tightly to the\narchitecture implementation. The alloctor also suffers from it\u0027s very\nbackwards nature as it has tied things together that should have no\ndependencies.\n\nTo solve the basic dynamic irq allocation problem two new architecture\nspecific functions are added: create_irq and destroy_irq.\n\ncreate_irq takes no input and returns an unused irq number, that won\u0027t be\nreused until it is returned to the free poll with destroy_irq. The irq then\ncan be used for any purpose although the only initial consumer is the msi\ncode.\n\ndestroy_irq takes an irq number allocated with create_irq and returns it to\nthe free pool.\n\nMaking this functionality per architecture increases the simplicity of the irq\nallocation code and increases it\u0027s flexibility.\n\ndynamic_irq_init() and dynamic_irq_cleanup() are added to automate the\nirq_desc initializtion that should happen for dynamic irqs.\n\nSigned-off-by: Eric W.

Though __d_find_alias(inode, 1)\nwill only return a dentry with DCACHE_DISCONNECTED set, it is possible for it\nto get cleared before the BUG_ON, and it is is not possible to lock against\nthat.\n\nThere are a couple of problems here. Firstly, the code doesn\u0027t match the\ncomment. The comment describes a \u0027disconnected\u0027 dentry as being IS_ROOT as\nwell as DCACHE_DISCONNECTED, however there is not testing of IS_ROOT anythere.\n\nA dentry is marked DCACHE_DISCONNECTED when allocated with d_alloc_anon, and\nremains DCACHE_DISCONNECTED while a path is built up towards the root. So a\ndentry can have a valid name and a valid parent and even grandparent, but will\nstill be DCACHE_DISCONNECTED until a path to the root is created. Once the\npath to the root is complete, everything in the path gets DCACHE_DISCONNECTED\ncleared. So the fact that DCACHE_DISCONNECTED isn\u0027t enough to say that a\ndentry is free to be spliced in with a given name. This can only be allowed\nif the dentry does not yet have a name, so the IS_ROOT test is needed too.\n\nHowever even adding that test to __d_find_alias isn\u0027t enough. As\nd_splice_alias drops dcache_lock before calling d_move to perform the splice,\nit could race with another thread calling d_splice_alias to splice the inode\nin with a different name in a different part of the tree (in the case where a\nfile has hard links). So that splicing code is only really safe for\ndirectories (as we know that directories only have one link). For\ndirectories, the caller of d_splice_alias will be holding i_mutex on the\n(unique) parent so there is no room for a race.\n\nA consequence of this is that a non-directory will never benefit from being\nspliced into a pre-exisiting dentry, but that isn\u0027t a problem. It is\nperfectly OK for a non-directory to have multiple dentries, some anonymous,\nsome not. And the comment for d_splice_alias says that it only happens for\ndirectories anyway.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "44c556000a31e8079cfbb9a42a7edb93ca6b589a", "tree": "cd4ee059c11fb1e30d9ef09d518715d9b329aa8f", "parents": [ "6b54dae2b0defb30babb0fe87b13463b9f4b2907" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Wed Oct 04 02:16:15 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 07:55:21 2006 -0700" }, "message": "[PATCH] knfsd: fix auto-sizing of nfsd request/reply buffers\n\ntotalram is measured in pages, not bytes, so PAGE_SHIFT must be used when\ntrying to find 1/4096 of RAM.\n\nCc: \"J.

This helps workloads using AUTH_SYS authentication\nover TCP.\n\nTesting was on a 4 CPU 4 NIC Altix using 4 IRIX clients, each with 16\nsynthetic client threads simulating an rsync (i.e. recursive directory\nlisting) workload reading from an i386 RH9 install image (161480 regular files\nin 10841 directories) on the server.

This patch drops both contribution\ninto the profile noise.\n\nNote that the above result overstates this value of this patch for most\nworkloads.

The server had 128 nfsd threads, which\nsizes the RA cache at 256 entries, of which only a handful were used. Flat\nprofiling shows nfsd_read(), including the inlined nfsd_get_raparms(), taking\n10.4% of each CPU. This patch drops the contribution from nfsd() to 1.71% for\neach CPU.\n\nSigned-off-by: Greg Banks \u003cgnb@melbourne.sgi.com\u003e\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "596bbe53eb3abfe7326b2f5e8afd614265c319c8", "tree": "31e1f008f8acb46d1a3a937538446a1447ed9c8f", "parents": [ "7adae489fe794e3e203ff168595f635d0b845e59" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Wed Oct 04 02:15:48 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 07:55:16 2006 -0700" }, "message": "[PATCH] knfsd: Allow max size of NFSd payload to be configured\n\nThe max possible is the maximum RPC payload.
