2008-04-08SUNRPC: don't call flush_dcache_page() with an invalid pointerTrond Myklebust
Fix a problem in _copy_to_pages(), whereby it may call flush_dcache_page() with an invalid pointer due to the fact that 'pgto' gets incremented beyond the end of the page array. Fix is to exit the loop without this unnecessary increment of pgto. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-02-01SUNRPC: Use unsigned string lengths in xdr_decode_string_inplaceChuck Lever
XDR strings, opaques, and net objects should all use unsigned lengths. To wit, RFC 4506 says: 4.2. Unsigned Integer An XDR unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0,4294967295]. ... 4.11. String The standard defines a string of n (numbered 0 through n-1) ASCII bytes to be the number n encoded as an unsigned integer (as described above), and followed by the n bytes of the string. After this patch, xdr_decode_string_inplace now matches the other XDR string and array helpers that take a string length argument.

2007-10-24SG: Change sg_set_page() to take length and offset argumentJens Axboe
Most drivers need to set length and offset as well, so may as well fold those three lines into one. Add sg_assign_page() for those two locations that only needed to set the page, where the offset/length is set outside of the function context. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2006-12-06rpc: move process_xdr_bufOlga Kornievskaia
Since process_xdr_buf() is useful outside of the kerberos-specific code, we move it to net/sunrpc/xdr.c, export it, and rename it in keeping with xdr_* naming convention of xdr.c. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2005-05-01[PATCH] DocBook: changes and extensions to the kernel documentationPavel Pisa
I have recompiled Linux kernel 2.6.11.5 documentation for me and our university students again. The documentation could be extended for more sources which are equipped by structured comments for recent 2.6 kernels. I have tried to proceed with that task. I have done that more times from 2.6.0 time and it gets boring to do same changes again and again. Linux kernel compiles after changes for i386 and ARM targets. I have added references to some more files into kernel-api book, I have added some section names as well. So please, check that changes do not break something and that categories are not too much skewed. I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved by kernel convention. Most of the other changes are modifications in the comments to make kernel-doc happy, accept some parameters description and do not bail out on errors. Changed <pid> to @pid in the description, moved some #ifdef before comments to correct function to comments bindings, etc. You can see result of the modified documentation build at http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz Some more sources are ready to be included into kernel-doc generated documentation. Sources has been added into kernel-api for now. Some more section names added and probably some more chaos introduced as result of quick cleanup work.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
