2010-08-11param: use ops in struct kernel_param, rather than get and set fns directlyRusty Russell
This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.

2010-08-10NFS: allow close-to-open cache semantics to apply to root of NFS filesystemNeil Brown
To obey NFS cache semantics, the client must verify the cached attributes when a file is opened. In most cases this is done by a call to d_validate as one of the last steps in path_walk. However for the root of a filesystem, d_validate is only ever called on the mounted-on filesystem (except when the path ends '.' or '..'). So NFS has no chance to validate the attributes. So, in nfs_opendir, we revalidate the attributes if the opened directory is the mountpoint. This may cause double-validation for "." and ".." lookups, but that is better than missing regular /path/name lookups completely.

2010-08-02vfs: re-introduce MAY_CHDIREric Paris
Currently MAY_ACCESS means that filesystems must check the permissions right then and not rely on cached results or the results of future operations on the object. This can be because of a call to sys_access() or because of a call to chdir() which needs to check search without relying on any future operations inside that dir. I plan to use MAY_ACCESS for other purposes in the security system, so I split the MAY_ACCESS and the MAY_CHDIR cases. Signed-off-by: Eric Paris <eparis@redhat.com> Acked-by: Stephen D.

2010-07-30nfs: include space for the NUL in root pathDan Carpenter
In root_nfs_name() it does the following: if (strlen(buf) + strlen(cp) > NFS_MAXPATHLEN) { printk(KERN_ERR "Root-NFS: Pathname for remote directory too long.\n"); return -1; } sprintf(nfs_export_path, buf, cp); In the original code if (strlen(buf) + strlen(cp) == NFS_MAXPATHLEN) then the sprintf() would lead to an overflow. Generally the rest of the code assumes that the path can have NFS_MAXPATHLEN (1024) characters and a NUL terminator so the fix is to add space to the nfs_export_path[] buffer.

2010-07-19mm: add context argument to shrinker callbackDave Chinner
The current shrinker implementation requires the registered callback to have global state to work from. This makes it difficult to shrink caches that are not global (e.g. per-filesystem caches).

2010-06-22NFSv41: Further cleanup for nfs4_sequence_doneTrond Myklebust
Instead of testing if the nfs_client has a session, we should be testing if the struct nfs4_sequence_res was set up with one. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-06-22NFSv4.1: Make nfs4_setup_sequence take a nfs_server argumentTrond Myklebust

2010-06-22NFSv4.1: Simplify nfs41_sequence_done()Trond Myklebust
Nobody uses the rpc_status parameter. It is not obvious why we need the struct nfs_client argument either, when we already have that information in the session. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
