* [PATCH] knfsd: add some new fsid typesNeilBrown2007-02-141-23/+76
| | | | | | | | | | | | | | | | | Add support for using a filesystem UUID to identify and export point in the filehandle. For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up too much room. For NFSv3+, we use the full 16 bytes, and possibly also a 64bit inode number for exports beneath the root of a filesystem. When generating an fsid to return in 'stat' information, use the UUID (hashed down to size) if it is available and a small 'fsid' was not specifically provided.

* [PATCH] knfsd: replace some warning ins nfsfh.h with BUG_ON or WARN_ONNeilBrown2007-01-261-11/+4
| | | | | | | | | | | A couple of the warnings will be followed by an Oops if they ever fire, so may as well be BUG_ON. Another isn't obviously fatal but has never been known to fire, so make it a WARN_ON.

* [PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2006-09-271-8/+2
| | | | | | | | | | | | | | | | This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+343
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!
