However, there were still some left:\n\n 8.46% reaim [kernel.kallsyms] [k] _raw_spin_lock\n |--42.21%-- d_path\n | proc_pid_readlink\n | SyS_readlinkat\n | SyS_readlink\n | system_call\n | __GI___readlink\n |\n |--40.97%-- sys_getcwd\n | system_call\n | __getcwd\n\nThe big one here is the rename_lock (seqlock) contention in d_path()\nand the getcwd system call. This patch will eliminate the need to take\nthe rename_lock while translating dentries into the full pathnames.\n\nThe need to take the rename_lock is to make sure that no rename\noperation can be ongoing while the translation is in progress. However,\nonly one thread can take the rename_lock thus blocking all the other\nthreads that need it even though the translation process won\u0027t make\nany change to the dentries.\n\nThis patch will replace the writer\u0027s write_seqlock/write_sequnlock\nsequence of the rename_lock of the callers of the prepend_path() and\n__dentry_path() functions with the reader\u0027s read_seqbegin/read_seqretry\nsequence within these 2 functions. As a result, the code will have to\nretry if one or more rename operations had been performed. In addition,\nRCU read lock will be taken during the translation process to make sure\nthat no dentries will go away. To prevent live-lock from happening,\nthe code will switch back to take the rename_lock if read_seqretry()\nfails for three times.\n\nTo further reduce spinlock contention, this patch does not take the\ndentry\u0027s d_lock when copying the filename from the dentries. Instead,\nit treats the name pointer and length as unreliable and just copy\nthe string byte-by-byte over until it hits a null byte or the end of\nstring as specified by the length. This should avoid stepping into\ninvalid memory address. The error cases are left to be handled by\nthe sequence number check.\n\nThe following code re-factoring are also made:\n1. Move prepend(\u0027/\u0027) into prepend_name() to remove one conditional\n check.\n2. Move the global root check in prepend_path() back to the top of\n the while loop.\n\nWith this patch, the _raw_spin_lock will now account for only 1.2%\nof the total CPU cycles for the short workload. This patch also has\nthe effect of reducing the effect of running perf on its profile\nsince the perf command itself can be a heavy user of the d_path()\nfunction depending on the complexity of the workload.\n\nWhen taking the perf profile of the high-systime workload, the amount\nof spinlock contention contributed by running perf without this patch\nwas about 16%. With this patch, the spinlock contention caused by\nthe running of perf will go away and we will have a more accurate\nperf profile.\n\nSigned-off-by: Waiman Long \u003cWaiman.Long@hp.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "ef9a61bef917e38f8e096f6df303329aed6cf467", "tree": "31cfe2444d0270e77ff8ef792df11591fed6075c", "parents": [ "b5f0998cae3d7ea56d3d8377e46328fe972b9546", "6c3b88970175e18a67eb8e55c4eba10614d0d5dc" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 09 10:33:19 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 09 10:33:19 2013 -0700" }, "message": "Merge tag \u0027for-linus-20130909\u0027 of git://git.infradead.org/linux-mtd\n\nPull mtd updates from David Woodhouse:\n -

This second call doesn\u0027t have a matching\nput_balloon_scratch_page() thus not restoring preempt count back. (Also, there\nis no put_balloon_scratch_page() in the error path.)\n\nIn addition, the second multicall uses __xen_mc_entry() which does not disable\ninterrupts. Rearrange xen_mc_* calls to keep interrupts off while performing\nmulticalls.\n\nThis commit fixes a regression introduced by:\n\ncommit ee0726407feaf504dff304fb603652fb2d778b42\nAuthor: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nDate: Tue Jul 23 17:23:54 2013 +0000\n\n xen/m2p: use GNTTABOP_unmap_and_replace to reinstate the original mapping\n\nSigned-off-by: Boris Ostrovsky \u003cboris.ostrovsky@oracle.com\u003e\nReviewed-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\n" }, { "commit": "9dd4b2944c46e1fdbd0a516c221c8a2670cbf005", "tree": "b60f541e77d6195286502b41c5d5b04ca50b1b5c", "parents": [ "23b7eaf8220721892975610dd0ae5c846a34dcb4" ], "author": { "name": "Rob Herring", "email": "rob.herring@calxeda.com", "time": "Thu Aug 29 07:43:52 2013 -0500" }, "committer": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Mon Sep 09 10:50:26 2013 +0000" }, "message": "ARM: xen: only set pm function ptrs for Xen guests\n\nxen_pm_init was unconditionally setting pm_power_off and arm_pm_restart\nfunction pointers.
