2005-06-24[PATCH] Fix for cx88-cards.c for DVICO-FusionHDTV 3 GOLD QMichael Krufky
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.

2005-06-24[PATCH] knfsd: nfsd4: initialize recovery directoryNeilBrown
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.

2005-06-24[PATCH] knfsd: nfsd4: allow multiple lockownersNeilBrown
>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: J.

2005-06-24[PATCH] knfsd: nfsd4: grace period endNeilBrown
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.

2005-06-24[PATCH] knfsd: nfsd4: simplify lease changingNeilBrown
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.

2005-06-24[PATCH] knfsd: nfsd4: fix probe_callbackNeilBrown
rpc_create_client was modified recently to do its own (synchronous) NULL ping of the server. We'd rather do that on our own, asynchronously, so that we don't have to block the nfsd thread doing the probe, and so that setclientid handling (hence, client mounts) can proceed normally whether the callback is succesful or not.

We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the fh_expire_type attribute. This is incorrect: 1. The spec actually only allows NOEXPIRE_WITH_OPEN when VOLATILE_ANY is also set. 2. Filehandles for open files can expire, if the file is removed and there is a reboot. 3. Filehandles are only volatile on rename in the nosubtree check case. Unfortunately, there's no way to indicate that we only expire on remove. So our only choice is FH4_VOLATILE_ANY. Although it's redundant, we also set FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually cause problems in practice and it seems possibly useful to give clients some way to distinguish that case.

2005-06-24[PATCH] oprofile: report anonymous region samplesJohn Levon
The below patch passes samples from anonymous regions to userspace instead of just dropping them. This provides the support needed for reporting anonymous-region code samples (today: basic accumulated results; later: Java and other dynamically compiled code). As this changes the format, an upgrade to the just-released 0.9 release of the userspace tools is required. This patch is based upon an earlier one by Will Cohen <wcohen@redhat.com> Signed-off-by: John Levon <levon@movementarian.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

tuner-core.c, tuner.h: - tuner-core changed to support multiple I2C devices used on some adapters; - Kconfig now has an option (CONFIG_TUNER_MULTI_I2C) to enable this new behavor; - By default, even enabling CONFIG_TUNER_MULTI_I2C, tuner-core emulates the old behavor, using first I2C device for both FM and TV; - There is a new i2c command (TUNER_SET_ADDR) to allow tuner clients to select I2C address for FM or TV tuner; - Tuner I2C dettach now generates a warning on syslog if failed. tuner-simple.c: - TVision TVF-8531MF and TVF-5533 MF tuner included. It uses, by default, I2C on 0xC2 address for TV and on 0xC0 for Radio. Both TV and FM Radio mode are working.
