2008-10-07NFS: Add options for finer control of the lookup cacheTrond Myklebust
Add the flag NFS_MOUNT_LOOKUP_CACHE_NONEG to turn off the caching of negative dentries. In reality what we do is to force nfs_lookup_revalidate() to always discard negative dentries. Add the flag NFS_MOUNT_LOOKUP_CACHE_NONE for enforcing stricter revalidation of dentries. It forces the revalidate code to always do a lookup instead of just checking the cached mtime of the parent directory. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2007-12-06NFS: Switch from intr mount option to TASK_KILLABLEMatthew Wilcox
By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr' mount option. We have to use _killable everywhere instead of _interruptible as we get rid of rpc_clnt_sigmask/sigunmask. Signed-off-by: Liam R. Howlett <howlett@gmail.com> Signed-off-by: Matthew Wilcox <willy@linux.intel.com>
2007-07-10NFS: Add the mount option "nosharecache"Trond Myklebust
Prior to David Howell's mount changes in 2.6.18, users who mounted different directories which happened to be from the same filesystem on the server would get different super blocks, and hence could choose different mount options. As long as there were no hard linked files that crossed from one subtree to another, this was quite safe. Post the changes, if the two directories are on the same filesystem (have the same 'fsid'), they will share the same super block, and hence the same mount options. Add a flag to allow users to elect not to share the NFS super block with another mount point, even if the fsids are the same. This will allow users to set different mount options for the two different super blocks, as was previously possible. It is still up to the user to ensure that there are no cache coherency issues when doing this, however the default behaviour will be to share super blocks whenever two paths result in the same fsid.

2007-04-30NFS: Added support to turn off the NFSv3 READDIRPLUS RPC.Steve Dickson
READDIRPLUS can be a performance hindrance when the client is working with large directories. In addition, some servers still have bugs in their implementations (e.g. Tru64 returns wrong values for the fsid). Add a mount flag to enable users to turn it off at mount time following the implementation in Apple's NFS client.

2005-06-22[PATCH] NFS: Add support for NFSv3 ACLsAndreas Gruenbacher
This adds acl support fo nfs clients via the NFSACL protocol extension, by implementing the getxattr, listxattr, setxattr, and removexattr iops for the system.posix_acl_access and system.posix_acl_default attributes. This patch implements a dumb version that uses no caching (and thus adds some overhead). (Another patch in this patchset adds caching as well.)

2005-04-16Linux-2.6.12-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!
