2010-05-26Btrfs: allow unaligned DIOChris Mason1-3/+35
In order to support DIO that isn't aligned to the filesystem blocksize, we fall back to buffered for any unaligned DIOs. Signed-off-by: Chris Mason <[email protected]>

2010-05-26Btrfs: Fix block generation verification raceYan, Zheng1-1/+1
After the path is released, the generation number got from block pointer is no long valid. The race may cause disk corruption, because verify_parent_transid() calls clear_extent_buffer_uptodate() when generation numbers mismatch.

2010-05-26Btrfs: fix preallocation and nodatacow checks in O_DIRECTChris Mason1-16/+140
The O_DIRECT code wasn't checking for multiple references on preallocated or nodatacow extents. This means it wasn't honoring snapshots properly. The fix here is to add an explicit check for multiple references This also fixes the math for selecting the correct disk block, making sure not to go past the end of the extent.

2010-05-26[S390] spp: remove KVM_AWARE_CMF config optionHeiko Carstens3-15/+2
This config option enables or disables three single instructions which aren't expensive. This is too fine grained. Besided that everybody who uses kvm would enable it anyway in order to debug performance problems. Just remove it.

2010-05-26[S390] kprobes: forbid probing of stnsm/stosm/epswHeiko Carstens1-0/+3
The probed instructions will be executed in a single stepped and irq disabled context. Therefore the results of stnsm, stosm and epsw would be wrong if probed. So let's just disallow probing of these functions. If really needed a fixup could be written for each of them, but I doubt it's worth it.

2010-05-26[S390] cmm: fix crash on module unloadHeiko Carstens1-9/+9
There might be a scheduled cmm_timer if the cmm module gets unloaded. That timer was not deleted during module unload and thus could lead to system crash later on. Besides that reorder function calls in module init and exit code to avoid a couple of other races which could lead to accesses to uninitialized data.

2010-05-26do_generic_file_read: clear page errors when issuing a fresh read of the pageJeff Moyer1-0/+6
I/O errors can happen due to temporary failures, like multipath errors or losing network contact with the iSCSI server. Because of that, the VM will retry readpage on the page. However, do_generic_file_read does not clear PG_error. This causes the system to be unable to actually use the data in the page cache page, even if the subsequent readpage completes successfully! The function filemap_fault has had a ClearPageError before readpage forever. This patch simply adds the same to do_generic_file_read.

2010-05-26backlight: add S6E63M0 AMOLED LCD Panel driverInKi Dae5-0/+1218
This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI interface also almost features for lcd panel driver has been implemented in here. and I added new structure common for all the lcd panel drivers to include/linux/lcd.h file. LCD Panel driver needs interfaces for controlling device power such as power on/off and reset. these interfaces are device specific so it should be implemented to machine code at this time, we should create new structure for registering these functions as callbacks and also a header file for that structure and finally registered callback functions would be called by lcd panel driver. such header file(including new structure for lcd panel) would be added for all the lcd panel drivers. If anyone provides common structure for registering such callback functions then we could reduce unnecessary header files for lcd panel. I thought that suitable anyone could be include/linux/lcd.h so a new lcd_platform_data structure was added there.
