results in random odd pty issues.\n\nIt re-introduced the buggy schedule_work() in flush_to_ldisc() that can\ncause endless work-loops (see commit a5660b41af6a: \"tty: fix endless\nwork loop when the buffer fills up\").\n\nIt also used an \"unsigned int\" return value fo the -\u003ereceive_buf()\nfunction, but then made multiple functions return a negative error code,\nand didn\u0027t actually check for the error in the caller.\n\nAnd it didn\u0027t actually work at all. BenH bisected down odd tty behavior\nto it:\n \"It looks like the patch is causing some major malfunctions of the X\n server for me, possibly related to PTYs. For example, cat\u0027ing a\n large file in a gnome terminal hangs the kernel for -minutes- in a\n loop of what looks like flush_to_ldisc/workqueue code, (some ftrace\n data in the quoted bits further down).\n\n ...\n\n Some more data: It -looks- like what happens is that the\n flush_to_ldisc work queue entry constantly re-queues itself (because\n the PTY is full ?) and the workqueue thread will basically loop\n forver calling it without ever scheduling, thus starving the consumer\n process that could have emptied the PTY.\"\n\nwhich is pretty much exactly the problem we fixed in a5660b41af6a.\n\nMilton Miller pointed out the \u0027unsigned int\u0027 issue.\n\nReported-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nReported-by: Milton Miller \u003cmiltonm@bga.com\u003e\nCc: Stefan Bigler \u003cstefan.bigler@keymile.com\u003e\nCc: Toby Gray \u003ctoby.gray@realvnc.com\u003e\nCc: Felipe Balbi \u003cbalbi@ti.com\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7b29dc21ea084be7ddfb536994a9cfae95337690", "tree": "799f5becd9484e53e09b5f620ebfd5315bdfe033", "parents": [ "9a2e0fb0893ddf595d0a372e681f5b98017c6d90", "dfe21582ac5ebc460dda98c67e8589dd506d02cd" ], "author": { "name": "John W.

In the loop in the\ninternal __domain_mapping() function, we simply detect if we are mapping:\n - size \u003e\u003d 2MiB, and\n - virtual address aligned to 2MiB, and\n - physical address aligned to 2MiB, and\n - on hardware that supports superpages.\n\n(and likewise for larger superpages).\n\nWe automatically use a superpage for such mappings. We never have to\nworry about *breaking* superpages, since we trust that we will always\n*unmap* the same range that was mapped. So all we need to do is ensure\nthat dma_pte_clear_range() will also cope with superpages.\n\nAdjust pfn_to_dma_pte() to take a superpage \u0027level\u0027 as an argument, so\nit can return a PTE at the appropriate level rather than always\nextending the page tables all the way down to level 1. Again, this is\nsimplified by the fact that we should never encounter existing small\npages when we\u0027re creating a mapping; any old mapping that used the same\nvirtual range will have been entirely removed and its obsolete page\ntables freed.\n\nProvide an \u0027intel_iommu\u003dsp_off\u0027 argument on the command line as a\nchicken bit.

This look up currently needs the acquisition of a\nlock to access the list of qos requests to find the qos target value,\nslowing down the entrance into idle state due to contention by multiple\ncpus to access this list. The contention is severe when there are a lot\nof cpus waking and going into idle. For example, for a simple workload\nthat has 32 pair of processes ping ponging messages to each other, where\n64 cpu cores are active in test system, I see the following profile with\n37.82% of cpu cycles spent in contention of pm_qos_lock:\n\n- 37.82% swapper [kernel.kallsyms] [k]\n_raw_spin_lock_irqsave\n - _raw_spin_lock_irqsave\n - 95.65% pm_qos_request\n menu_select\n cpuidle_idle_call\n - cpu_idle\n 99.98% start_secondary\n\nA better approach will be to cache the updated pm_qos target value so\nreading it does not require lock acquisition as in the patch below.\nWith this patch the contention for pm_qos_lock is removed and I saw a\n2.2X increase in throughput for my message passing workload.\n\ncc: stable@kernel.org\nSigned-off-by: Tim Chen

To do that it currently looks up\nsecurity.capability on EVERY write (even for non executables) to decide\nwhether to drop it or not.\n\nIn btrfs this causes an additional tree walk, hitting some per file system\nlocks and quite bad scalability. In a simple read workload on a 8S\nsystem I saw over 90% CPU time in spinlocks related to that.\n\nChris Mason tells me this is also a problem in ext4, where it hits\nthe global mbcache lock.\n\nThis patch adds a simple per inode to avoid this problem. We only\ndo the lookup once per file and then if there is no xattr cache\nthe decision. All xattr changes clear the flag.\n\nI also used the same flag to avoid the suid check, although\nthat one is pretty cheap.\n\nA file system can also set this flag when it creates the inode,\nif it has a cheap way to do so. This is done for some common file systems\nin followon patches.\n\nWith this patch a major part of the lock contention disappears\nfor btrfs. Some testing on smaller systems didn\u0027t show significant\nperformance changes, but at least it helps the larger systems\nand is generally more efficient.\n\nv2: Rename is_sgid. add file system helper.\nCc: chris.mason@oracle.com\nCc: josef@redhat.com\nCc: viro@zeniv.linux.org.uk\nCc: agruen@linbit.com\nCc: Serge E.

transports\n\nTI-RPC introduces the capability of performing RPC over AF_LOCAL\nsockets. It uses this mainly for registering and unregistering\nlocal RPC services securely with the local rpcbind, but we could\nalso conceivably use it as a generic upcall mechanism.\n\nThis patch provides a client-side only implementation for the moment.\nWe might also consider a server-side implementation to provide\nAF_LOCAL access to NLM (for statd downcalls, and such like).\n\nAutobinding is not supported on kernel AF_LOCAL transports at this\ntime. Kernel ULPs must specify the pathname of the remote endpoint\nwhen an AF_LOCAL transport is created. rpcbind supports registering\nservices available via AF_LOCAL, so the kernel could handle it with\nsome adjustment to -\u003erpcbind and -\u003eset_port. But we don\u0027t need this\nfeature for doing upcalls via well-known named sockets.\n\nThis has not been tested with ULPs that move a substantial amount of\ndata. Thus, I can\u0027t attest to how robust the write_space and\ncongestion management logic is.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "10799db60cbc4f990dd69eb49883477095c66af7", "tree": "b87ac6acaa48f4f59f5d6a0b11490105876952e1", "parents": [ "aaab184276a6e20834f63735d433f94ef52a0497", "c5c177b4aca83338781e72be2e6dd1601c560cb3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri May 27 11:16:27 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri May 27 11:16:27 2011 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:\n net: Kill ratelimit.h dependency in linux/net.h\n net: Add linux/sysctl.h includes where needed.\n net: Kill ether_table[] declaration.\n inetpeer: fix race in unused_list manipulations\n atm: expose ATM device index in sysfs\n IPVS: bug in ip_vs_ftp, same list heaad used in all netns.\n bug.h: Move ratelimit warn interfaces to ratelimit.h\n bonding: cleanup module option descriptions\n net:8021q:vlan.c Fix pr_info to just give the vlan fullname and version.\n net: davinci_emac: fix dev_err use at probe\n can: convert to %pK for kptr_restrict support\n net: fix ETHTOOL_SFEATURES compatibility with old ethtool_ops.set_flags\n netfilter: Fix several warnings in compat_mtw_from_user().\n netfilter: ipset: fix ip_set_flush return code\n netfilter: ipset: remove unused variable from type_pf_tdel()\n netfilter: ipset: Use proper timeout value to jiffies conversion\n" }, { "commit": "c5c177b4aca83338781e72be2e6dd1601c560cb3", "tree": "b3640c3100d491d9c14fb677ced3a0e4dd780c6f", "parents": [ "bee95250f015ffc3a6efb99516489e70d1b52da2" ], "author": { "name": "David S.
