2010-05-10nilfs2: add kernel doc comments to persistent object allocator functionsRyusuke Konishi

2010-05-10nilfs2: change sc_timer from a pointer to an embedded one in struct ↵Li Hong
nilfs_sc_info In nilfs_segctor_thread(), timer is a local variable allocated on stack. Its address can't be set to sci->sc_timer and passed in several procedures. It works now by chance, just because other procedures are called by nilfs_segctor_thread() directly or indirectly and the stack hasn't been deallocated yet.

2010-05-10nilfs2: remove nilfs_segctor_init() in segment.cLi Hong
There are only two lines of code in nilfs_segctor_init(). From a logic design view, the first line 'sci->sc_seq_done = sci->sc_seq_request;' should be put in nilfs_segctor_new(). Even in nilfs_segctor_new(), this initialization is needless because sci is kzalloc-ed. So nilfs_segctor_init() is only a wrap call to nilfs_segctor_start_thread().

2010-05-10nilfs2: insert checkpoint number in segment summary headerRyusuke Konishi
This adds a field to record the latest checkpoint number in the nilfs_segment_summary structure. This will help to recover the latest checkpoint number from logs on disk. This field is intended for crucial cases in which super blocks have lost pointer to the latest log. Even though this will change the disk format, both backward and forward compatibility is preserved by a size field prepared in the segment summary header.

2010-05-10nilfs2: change default of 'errors' mount option to 'remount-ro' modeRyusuke Konishi
Like ext3, nilfs has 'errors' mount option to allow specifying desired behavior on severe errors. Currently, the default action is 'errors=continue' and has potential to advance filesystem corruption for severe errors. This will change the action to 'errors=remount-ro' to avoid the issue.

2010-05-09cpuidle: Fix incorrect optimizationArjan van de Ven
commit 672917dcc78 ("cpuidle: menu governor: reduce latency on exit") added an optimization, where the analysis on the past idle period moved from the end of idle, to the beginning of the new idle. Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

2010-05-07md: restore ability of spare drives to spin down.NeilBrown
Some time ago we stopped the clean/active metadata updates from being written to a 'spare' device in most cases so that it could spin down and say spun down. Device failure/removal etc are still recorded on spares. However commit 51d5668cb2e3fd1827a55 broke this 50% of the time, depending on whether the event count is even or odd. The change log entry said: This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, how ever the code makes no attempt to create that alignment, so it could take arbitrarily long. So when we find that clean/dirty is not aligned with odd/even, force a second metadata-update immediately. There are already cases where a second metadata-update is needed immediately (e.g. when a device fails during the metadata update). We just piggy-back on that.

2010-05-06V4L/DVB: saa7146: fix regression of the av7110/budget-av driverHans Verkuil
An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late) caused a new regression in the av7110 driver. Reverted the old fix and fixed the problem in the mxb driver instead. Tested on mxb and budget-av cards. The real problem is that the saa7146 framework has separate probe() and attach() driver callbacks which should be rolled into one. This is now done for the mxb driver, but others should do the same. Lack of hardware makes this hard to do, though. I hope to get hold of some hexium cards and then I can try to improve the framework to prevent this from happening again.
