2010-12-22writeback: do uninterruptible sleep in balance_dirty_pages()Wu Fengguang1-1/+1
Using TASK_INTERRUPTIBLE in balance_dirty_pages() seems wrong. If it's going to do that then it must break out if signal_pending(), otherwise it's pretty much guaranteed to degenerate into a busywait loop. Plus we *do* want these processes to appear in D state and to contribute to load average. So it should be TASK_UNINTERRUPTIBLE. -- Andrew Morton Signed-off-by: Wu Fengguang <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2010-12-22logfs: fix "Kernel BUG at readwrite.c:1193"Prasad Joshi1-0/+3
This happens when __logfs_create() tries to write a new inode to the disk which is full. __logfs_create() associates the transaction pointer with inode. During the logfs_write_inode() function call chain this transaction pointer is moved from inode to page->private using function move_inode_to_page (do_write_inode() -> inode_to_page() -> move_inode_to_page) When the write inode fails, the transaction is aborted and iput is called on the failed inode. During delete_inode the same transaction pointer associated with the page is getting used. Thus causing kernel BUG. The patch checks for error in write_inode() and restores the page->private to NULL.

The same mutex is used in address_space_operations->writepage(), and a call to writepage() could be triggered as a result of memory allocation in btree_insert32, causing a deadlock.

2010-12-22mm: vmscan: tracepoint: account for scanned pages similarly for both ftrace ↵Mel Gorman1-1/+10
and vmstat When correlating ftrace results with /proc/vmstat, I noticed that the reporting scripts value for "pages scanned" differed significantly. Both values were "right" depending on how you look at it. The difference is due to vmstat only counting scanning of the inactive list towards pages scanned. The analysis script for the tracepoint counts active and inactive list yielding a far higher value than vmstat. The resulting scanning/reclaim ratio looks much worse. The tracepoint is ok but this patch updates the reporting script so that the report values for scanned are similar to vmstat.

Since the libdwfl library before 0.148 fails to analyze live kernel debuginfo, 'perf probe --list' compiled with those old libdwfl sometimes crashes. To avoid that bug, perf probe does not use libdwfl's live kernel analysis routine when it is compiled with older libdwfl. Side effect: perf with older libdwfl doesn't support listing probe in modules with source code line. Those could be shown by symbol+offset.

So, this patch sets SDIO transfer types: SDIO block and SDIO byte transfers instead of using ordinary MMC block transfers.

2010-12-21mmc: at91_mci: fix multiblock SDIO transfersYauhen Kharuzhy2-4/+11
The AT91 MCI has special SDIO transfer types: SDIO block and SDIO byte transfers, but at91_mci driver doesn't use them and handles all SDIO transfers as ordinary MMC block transfers. This causes problems for multiple-block SDIO transfers (in particular for 256-bytes blocks). Fix this situation by checking the opcode for SDIO CMD53 and setting the transfer type in the AT91_MCI_CMDR register properly. This patch was tested with libertas SDIO driver: problem with TX timeouts on big packets was eliminated.
