Our client\u0027s\nnfs_client_id4 string is unique for each server IP address.\n\nAn NFSv4 server is obligated to wipe all NFSv4 state associated with\nan nfs_client_id4 string when the client presents the same\nnfs_client_id4 string along with a changed SETCLIENTID boot verifier.\n\nWhen our client unmounts the last of a server\u0027s shares, it destroys\nthat server\u0027s struct nfs_client.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here.

Moreover, servers may have a difficult time determining when\nthey can reap their state owner table, thanks to gray areas in the\nNFSv4 protocol specification. Thus clients should be careful to reuse\nstate owners when possible.\n\nCurrently Linux is not too careful. When a user has closed all her\nfiles on one mount point, the state owner\u0027s reference count goes to\nzero, and it is released. The next OPEN allocates a new one. A\nworkload that serially opens and closes files can run through a large\nnumber of open owners this way.\n\nWhen a state owner\u0027s reference count goes to zero, slap it onto a free\nlist for that nfs_server, with an expiry time. Garbage collect before\nlooking for a state owner. This makes state owners for active users\navailable for re-use.\n\nNow that there can be unused state owners remaining at umount time,\npurge the state owner free list when a server is destroyed. Also be\nsure not to reclaim unused state owners during state recovery.\n\nThis change has benefits for the client as well. For some workloads,\nthis approach drops the number of OPEN_CONFIRM calls from the same as\nthe number of OPEN calls, down to just one. This reduces wire traffic\nand thus open(2) latency.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "888ef2e3f8b7b8daeb031bfb4ad1fd4fa817e193", "tree": "d50044d998e636232f1110324d6485a92c20daf2", "parents": [ "f895c53f8ace3c3e49ebf9def90e63fc6d46d2bf" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Fri Feb 05 03:45:03 2010 -0800" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Mar 02 12:16:12 2010 -0500" }, "message": "nfs: kill renewd before clearing client minor version\n\nrenewd should be synchronously killed before we destroy the session in\nnfs4_clear_minor_version\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\n[Trond.Myklebust@netapp.com: clean up to remove \u0027unused function\nwarning when !CONFIG_NFS_V4]\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "2449ea2e191123729b2dc37a06fcb9d6ea7e2736", "tree": "f5b71099baefb6c550511b3d5f3da26b8c384454", "parents": [ "7b183d0d432ab3525ae29511a5348ead3e790620" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Sat Dec 05 13:36:55 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Dec 05 13:36:55 2009 -0500" }, "message": "nfs41: V2 adjust max_rqst_sz, max_resp_sz w.r.t to rsize, wsize\n\nThe v4.1 client should take into account the desired rsize, wsize when\nnegotiating the max size in CREATE_SESSION.
