2011-07-26libceph: don't time out osd requests that haven't been receivedSage Weil
Keep track of when an outgoing message is ACKed (i.e., the server fully received it and, presumably, queued it for processing). Time out OSD requests only if it's been too long since they've been received. This prevents timeouts and connection thrashing when the OSDs are simply busy and are throttling the requests they read off the network.

2011-07-26ceph: only queue capsnap if caps are dirtySage Weil
We used to go into this branch if i_wrbuffer_ref_head was non-zero. This was an ancient check from before we were careful about dealing with all kinds of caps (and not just dirty pages). It is cleaner to only queue a capsnap if there is an actual dirty cap. If we are racing with... something...we will end up here with ci->i_wrbuffer_refs but no dirty caps.

2011-07-26ceph: fix snap writeback when racing with writesSage Weil
There are two problems that come up when we try to queue a capsnap while a write is in progress: - The FILE_WR cap is held, but not yet dirty, so we may queue a capsnap with dirty == 0. That will crash later in __ceph_flush_snaps(). Or on the FILE_WR cap if a write is in progress. - We may not have i_head_snapc set, which causes problems pretty quickly. Look to the snaprealm in this case. Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

2011-07-26ceph: add F_SYNC file flag to force sync (non-O_DIRECT) ioSage Weil
This allows us to force IO through the sync path which you normally only get when multiple clients are reading/writing to the same file or by mounting with -o sync. Among other things, this lets test programs verify correctness with a single mount. Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

2011-07-26ALSA: hda - Cirrus Logic CS421x supportTim Howe
This update includes the changes necessary for supporting the CS421x family of codecs. Previously this file only supported the CS420x family of codecs. This file also contains init verbs to correct several issues in the CS421x hardware. Behavior between the CS421x and CS420x codec families is similar, so several functions have been reused with "if" statements to determine which codec family (CS421x or CS420x) is present. Also, this file will be updated sometime in the near future in order to add support for a system using CS421x that requires mono mix on the speaker output only.

2011-07-26ALSA: hda - Allow codec-specific set_power_state opsTakashi Iwai
The procedure for codec D-state change may have exceptional cases depending on the codec chip, such as a longer delay or suppressing D3. This patch adds a new codec ops, set_power_state() to override the system default function. For ease of porting, snd_hda_codec_set_power_to_all() helper function is extracted from the default set_power_state() function. As an example, the Conexant codec-specific delay is removed from the default routine but moved to patch_conexant.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-07-26ext4: fix data corruption in inodes with journalled dataJan Kara
When journalling data for an inode (either because it is a symlink or because the filesystem is mounted in data=journal mode), ext4_evict_inode() can discard unwritten data by calling truncate_inode_pages(). This is because we don't mark the buffer / page dirty when journalling data but only add the buffer to the running transaction and thus mm does not know there are still unwritten data. Fix the problem by carefully tracking transaction containing inode's data, committing this transaction, and writing uncheckpointed buffers when inode should be reaped.
