The implementation enables to work with a server talking 9P2000.u. However, it

strings and maximum unsigned values.

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.

Change the signature of puffs_respcmp to return -1,0,1 for smaller,
equal, larger, respectively instead of 0/1 for non/equal. This
will allow sorting the buffers for faster matching in libpuffs.
While here, change the name from respcmp to framecmp, as that better
reflects the purpose.
NOTE! there is no obvious way to make compilation fail for file
systems which may already be using this feature (although I don't
think there are any outside our tree, as the feature is two weeks
old). Nevertheless, non-updated file systems will fail very quickly.

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.

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

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

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.

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.

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.

whole chmod would fail. So supply the file type as part of the
