This patch adds version and srcversion files to /sys/module/${modulename} containing the version and srcversion fields of the module's modinfo section (if present). /sys/module/e1000 |-- srcversion `-- version This patch differs slightly from the version posted in January, as it now uses the new kstrdup() call in -mm. Why put this in sysfs? a) Tools like DKMS, which deal with changing out individual kernel modules without replacing the whole kernel, can behave smarter if they can tell the version of a given module. The autoinstaller feature, for example, which determines if your system has a "good" version of a driver (i.e. if the one provided by DKMS has a newer verson than that provided by the kernel package installed), and to automatically compile and install a newer version if DKMS has it but your kernel doesn't yet have that version. b) Because sysadmins manually, or with tools like DKMS, can switch out modules on the file system, you can't count on 'modinfo foo.ko', which looks at /lib/modules/${kernelver}/... actually matching what is loaded into the kernel already. Hence asking sysfs for this. c) as the unbind-driver-from-device work takes shape, it will be possible to rebind a driver that's built-in (no .ko to modinfo for the version) to a newly loaded module. sysfs will have the currently-built-in version info, for comparison. d) tech support scripts can then easily grab the version info for what's running presently - a question I get often. There has been renewed interest in this patch on linux-scsi by driver authors. As the idea originated from GregKH, I leave his Signed-off-by: intact, though the implementation is nearly completely new. Compiled and run on x86 and x86_64.

Add support for tuner#60: Thomson DDT 7611 (ATSC/NTSC) Change tuner in card#28 (DViCO FusionHDTV3 Gold-T) from tuner=52 (Tuner Thomson DDT 7610) to tuner=60 (Tuner Thomson DDT 7611) Signed-off-by:

Even though it says DViCO FusionHDTV3 Gold-Q on the box, Gold-T is printed on the card. This fix corrects the error in all places, and corrects the tuner name Thomson DDT 7611 (ATSC/NTSC) in the documentation. This applies against 2.6.12-rc5-mm2 after applying Manueal Capinha's patch "Add support for PixelView Ultra Pro in v4l" (because of the change from card=27 to card=28) Signed-off-by:

Manuel Capinha authored
The following patch adds support for the PixelView Ultra Pro video capture card in v4l. - It removes the remote control key definitions from ir-kbd-gpio.c and moves them to ir-common.c so that they can be shared between bt878 and cx88 based cards. - The patch also moves the FUSIONHDTV_3_GOLD_Q card from number 27 to 28 to regain compatibility with the V4L cvs. Signed-off-by:

This patch allows full analog functionality for the DViCO FusionHDTV3 Gold-Q, 18ac:d820 which has a Conexant cx23882, Thompson7611, and LG 3202. It does NOT yet support digital decoding or digital audio without the internal analog audio jack connected to the sound board, but it works perfectly in analog mode. Signed-off-by:

This patch adds the code to create and remove client subdirectories from the recovery directory, as described in the previous patch comment. Signed-off-by:

NFSv4 clients are required to know what state they have on the server so that they can reclaim it on server reboot. However, it is possible for pathalogical combinations of server reboots and network partitions to leave a client in a state where it cannot know whether it has lost its state on the server. For this reason, rfc3530 requires that we store some information about clients to stable storage. So we maintain a directory /var/lib/nfs/v4recovery with a subdirectory for each client with active state. We leave open the possibility of including files underneath each such subdirectory with information about the client, but for now the subdirectories are empty. We create a client subdirectory whenever a client makes its first non-reclaim open_confirm. We remove a client subdirectory whenever either a) its lease expires, or b) the grace period ends without it reclaiming anything. When handling reclaims, we allow the reclaim if and only if the client doing the reclaim has a subdirectory. This patch adds just the code to scan the recovery directory on nfsd startup.

The cb_parsed field is only used by probe_callback, to determine whether the callback information has been filled in by setclientid. But there is no way that probe_callback() can be called without that having already happened, so that check is superfluous, as is cb_parsed. Signed-off-by:

>From the language of rfc3530 section 8.1.3 (e.g., the suggestion that a "process id" might be a reasonable lockowner value) it's conceivable that a client might want to use the same lockowner string on multiple files, so we may as well allow that. We expect each use of open_to_lockowner to create a distinct seqid stream, though. For now we're also allowing multiple uses of open_to_lockowner with the same open, though it seems unlikely clients would actually do that. Also add a comment reminding myself of some very non-scalable data structures. Signed-off-by:

Trivial renaming patch: I can never remember, while looking at various lists relating the nfsd4 state structures, which are the "heads" and which are items on other lists, or which structures are actually on the various lists. The following convention helps me: given structures foo and bar, with foo containing the head of a list of bars, use "bars" for the name of the head of the list contained in the struct foo, and use "per_foo" for the entries in the struct bars. Already done for struct nfs4_file; go ahead and do it for the other nfsd4 state structures. Signed-off-by:

Setclientid_confirm code confused states 1 and 3 (numbering from the IMPLEMENTATION section of rfc3530, section 14.2.33). Fix this. State 1 allows the client to change the callback channel on the fly. We don't implement this currently, so just turn off the callback channel in this case. From: Fred Isaman Signed-off-by:

For the purposes of reboot recovery, we want to do some work during the transition period at the end of the grace period. Some of that work must be guaranteed to have a certain relationship with the end of the grace period, so we want to control the transition there. Our approach is to modify the in_grace() checks to consult a global variable instead of checking the time directly, to schedule the first run of the laundromat thread at the end of the grace period, and to set the global end-of-grace-period there.

For the purposes of reboot recovery we keep a directory with subdirectories each having a name that is the ascii hex representation of the md5 sum of a client identifier for an active client. This adds the code to calculate that name. We also use it for the purposes of comparing clients, so if someone ever manages to find two client names that are md5 collisions, then we'll return clid_inuse to the second. Signed-off-by:

NeilBrown authored
The only way the protocol gives to change the lease time on the fly is to simulate a reboot. We don't have that completely right in the current code; among other things, we should probably put lockd in grace too while we do this. For now, let's just keep this simple, and wait till the next time nfsd starts to register any changes in lease time. If the administrator really wants to change the lease time *now*, they can go ahead and bring nfsd down and then back up again after changing the lease time. Also remove the "if (reclaim_str_hashtbl_size == 0)" case, a shortcut which skips the grace period if we know of no clients in need of recovery. This isn't going to work well with nlm. Signed-off-by:
