riastradh | mount_9p(8): Implement pathconf stub.
Doesn't actually do anything useful -- it just returns EINVAL as pathconf is supposed to for unknown pathconf key names; by default, it will return ENOTSUPP, which leads applications like ls(1) to print:
ls: /mnt/.git: Operation not supported
This is a little silly; perhaps puffs should use EINVAL itself instead of ENOTSUPP. But this change is less risky for now.

ozaki-r | mount_9p: fix writing to a file opened with write-only mode
With the page cache, writing data to a file may demand to read contents from a storage to fill a page in the page cache first.
Opening a file with write-only mode by a user lets a mount_9p process open a file with write-only mode too at a 9p server. Thus, a read request to the file from the page cache fails.
So we need to open a file always with read mode (internally) even if it is opened with write-only mode by a user.
Note that the change doesn't mean that mount_9p allows users to read contents from a file that is opened with write-only mode.

uwe | noderemove - do not call puffs_setback here. noderemove is called from rename (for existing target) and calling setback is not appropriate in that context. Do that call instead directly in the callers (remove, rmdir).

ozaki-r | mount_9p: add initial support for 9P2000.u
The implementation enables to work with a server talking 9P2000.u. However, it doesn't use the extended fields yet; it just ignores those of received messages and sets "please ignore" values to those of sending messages such as zero-length strings and maximum unsigned values.
The feature is enabled by the -u option.

pooka | * Apparently u9fs returns the inode number as the unique qidpath. This is fairly annoying if browsing a hierarchy with multiple file systems mounted, since at least inode 2 is fairly common. Compensate by comparing modification time also. Not perfect, but .... * Don't loop eternally if we attempt to read at or past EOF. Fixes reading files on a non-cached mount.

Ok, ok, a few more words about it: stop holding puffs_cc as a holy value and passing it around to almost every possible place (popquiz: which kernel variable does this remind you of?). Instead, pass the natural choice, puffs_usermount, and fetch puffs_cc via puffs_cc_getcc() only in routines which actually need it. This not only simplifies code, but (thanks to the introduction of puffs_cc_getcc()) enables constructs which weren't previously sanely possible, say layering as a curious example.
There's still a little to do on this front, but this was the major fs interface blast.

The whole lookup procedure should be done in a smarter fashion, but this is the quickie fix to get things working again.

pooka | If mode is set, the uppermost byte specifying the type must be correctly, otherwise the file server will attempt a conversion. Specifically, if the directory bit is not set when changing the permissions for a directory, a conversion from directory to regular file would be attempted and naturally it being unsupported the whole chmod would fail. So supply the file type as part of the file mode.

pooka | Alter the strategy for reading/writing a bit. First of all, use PUFFS_KFLAG_WTCACHE. Second, create separate fids for reading and writing. If opening for read, open a read-only fid and for write a write-only fid; use these for reading and writing. When the open-count for a node drops to zero, clunk both. This avoids hitting the fid limit when accessing large directory hierarchies.
Two problems remain: * does not take credentials into account, although we can only mount the remote 9P file server with one set of credentials, so not a huge worry * doesn't work for the open/mmap/close/access_memory_window case, but that will require some further kernel changes
