      "message": "oprofile: fix race condition in event_buffer free\n\nLooking at the 2.6.31-rc9 code, it appears there is a race condition\nin the event_buffer cleanup code path (shutdown). This could lead to\nkernel panic as some CPUs may be operating on the event buffer AFTER\nit has been freed. The attached patch solves the problem and makes\nsure CPUs check if the buffer is not NULL before they access it as\nsome may have been spinning on the mutex while the buffer was being\nfreed.\n\nThe race may happen if the buffer is freed during pending reads.

The multiplexing feature\nenables OProfile to gather more events than counters are provided by\nthe hardware. This is realized by switching between events at an user\nspecified time interval.\n\nA new file (/dev/oprofile/time_slice) is added for the user to specify\nthe timer interval in ms. If the number of events to profile is higher\nthan the number of hardware counters available, the patch will\nschedule a work queue that switches the event counter and re-writes\nthe different sets of values into it. The switching mechanism needs to\nbe implemented for each architecture to support multiplexing. This\npatch only implements AMD CPU support, but multiplexing can be easily\nextended for other models and architectures.\n\nThere are follow-on patches that rework parts of this patch.\n\nSigned-off-by: Jason Yeh \u003cjason.yeh@amd.com\u003e\nSigned-off-by: Robert Richter \u003crobert.richter@amd.com\u003e\n"

So it\u0027s\nsad to see it going neglected.\n\nWith CONFIG_PROFILING turned on (which is probably the common case at least\nfor distros and kernel developers), sizeof(struct dcache) \u003d\u003d 208 here\n(64-bit). This gives 19 objects per slab.\n\nI packed d_mounted into a hole, and took another 4 bytes off the inline\nname length to take the padding out from the end of the structure. This\nshinks it to 200 bytes. I could have gone the other way and increased the\nlength to 40, but I\u0027m aiming for a magic number, read on...\n\nI then got rid of the d_cookie pointer. This shrinks it to 192 bytes. Rant:\nwhy was this ever a good idea? The cookie system should increase its hash\nsize or use a tree or something if lookups are a problem. Also the \"fast\ndcookie lookups\" in oprofile should be moved into the dcookie code -- how\ncan oprofile possibly care about the dcookie_mutex? It gets dropped after\nget_dcookie() returns so it can\u0027t be providing any sort of protection.\n\nAt 192 bytes, 21 objects fit into a 4K page, saving about 3MB on my system\nwith ~140 000 entries allocated. 192 is also a multiple of 64, so we get\nnice cacheline alignment on 64 and 32 byte line systems -- any given dentry\nwill now require 3 cachelines to touch all fields wheras previously it\nwould require 4.\n\nI know the inline name size was chosen quite carefully, however with the\nreduction in cacheline footprint, it should actually be just about as fast\nto do a name lookup for a 36 character name as it was before the patch (and\nfaster for other sizes). The memory footprint savings for names which are\n\u003c\u003d 32 or \u003e 36 bytes long should more than make up for the memory cost for\n33-36 byte names.\n\nPerformance is a feature...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n"

      "message": "oprofile: port to the new ring_buffer\n\nThis patch replaces the current oprofile cpu buffer implementation\nwith the ring buffer provided by the tracing framework. The motivation\nhere is to leave the pain of implementing ring buffers to others. Oh,\nno, there are more advantages. Main reason is the support of different\nsample sizes that could be stored in the buffer. Use cases for this\nare IBS and Cell spu profiling. Using the new ring buffer ensures\nvalid and complete samples and allows copying the cpu buffer stateless\nwithout knowing its content. Second it will use generic kernel API and\nalso reduce code size. And hopefully, there are less bugs.\n\nSince the new tracing ring buffer implementation uses spin locks to\nprotect the buffer during read/write access, it is difficult to use\nthe buffer in an NMI handler. In this case, writing to the buffer by\nthe NMI handler (x86) could occur also during critical sections when\nreading the buffer. To avoid this, there are 2 buffers for independent\nread and write access. Read access is in process context only, write\naccess only in the NMI handler. If the read buffer runs empty, both\nbuffers are swapped atomically. There is potentially a small window\nduring swapping where the buffers are disabled and samples could be\nlost.\n\nUsing 2 buffers is a little bit overhead, but the solution is clear\nand does not require changes in the ring buffer implementation. It can\nbe changed to a single buffer solution when the ring buffer access is\nimplemented as non-locking atomic code.\n\nThe new buffer requires more size to store the same amount of samples\nbecause each sample includes an u32 header. Also, there is more code\nto execute for buffer access. Nonetheless, the buffer implementation\nis proven in the ftrace environment and worth to use also in oprofile.\n\nPatches that changes the internal IBS buffer usage will follow.\n\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Robert Richter \u003crobert.richter@amd.com\u003e\n"

Data\nis added to the buffers from in interrupt context.  The data\nis periodically pushed to the kernel buffer via a new Oprofile\nfunction oprofile_put_buff(). The oprofile_put_buff() function\nis called via a work queue enabling the funtion to acquire the\nmutex lock.\n\nThe existing user controls for adjusting the per CPU buffer\nsize is used to control the size of the per SPU buffers.\nSimilarly, overflows of the SPU buffers are reported by\nincrementing the per CPU buffer stats.  This eliminates the\nneed to have architecture specific controls for the per SPU\nbuffers which is not acceptable to the OProfile user tool\nmaintainer.\n\nThe export of the oprofile add_event_entry() is removed as it\nis no longer needed given this patch.\n\nNote, this patch has not addressed the issue of indexing arrays\nby the spu number.  This still needs to be fixed as the spu\nnumbering is not guarenteed to be 0 to max_num_spus-1.\n\nSigned-off-by: Carl Love \u003ccarll@us.ibm.com\u003e\nSigned-off-by: Maynard Johnson \u003cmaynardj@us.ibm.com\u003e\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Acked-by: Robert Richter \u003crobert.richter@amd.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n"

      "message": "[PATCH] VFS: Permit filesystem to override root dentry on mount\n\nExtend the get_sb() filesystem operation to take an extra argument that\npermits the VFS to pass in the target vfsmount that defines the mountpoint.\n\nThe filesystem is then required to manually set the superblock and root dentry\npointers.  For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing.  In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n     pointer argument and return an integer, so most filesystems have to change\n     very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n     normally call simple_set_mnt() to instantiate the vfsmount. This will\n     always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n     dcache upon superblock destruction rather than shrink_dcache_anon().\n\n     This is required because the superblock may now have multiple trees that\n     aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n     currently called functions assume that the whole tree is rooted at s_root,\n     and that anonymous dentries are not the roots of trees which results in\n     dentries being left unculled.\n\n     However, with the way NFS superblock sharing are currently set to be\n     implemented, these assumptions are violated: the root of the filesystem is\n     simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n     inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n     with child trees.\n\n     [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n     changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
