* m68knommu: fix use of un-defined _TIF_WORK_MASKGreg Ungerer2011-02-083-3/+0Star
| | | | | | | | | | | | | | The _TIF_WORK_MASK definition was removed in the clean up of MMU and non-MMU arch/m68k/include/asm/thread_info*.h files (this was commit cddafa3500fde4a07e5bf899ec97a04069f8f7ce, "merge MMU and non-MMU thread_info.h"). It didn't get cleaned out of the entry.S code for the 68328 and 68360 based platforms. And it was replaced by a hard coded constant mask for coldfire platforms. There is currently no need to mask any of these bits, so fix all uses (and former uses) to check for any non-zero value. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AACI TRM requires the MAINCR enable bit to be held zero for two bitclk cycles plus three apb_pclk cycles. Use a delay of 1us to ensure this.

| * | | | Btrfs: exclude super blocks when we read in block groupsJosef Bacik2011-02-061-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has been resulting in a BUT_ON(ret) after btrfs_reserve_extent in btrfs_cow_file_range. The reason is we don't actually calculate the bytes_super for a block group until we go to cache it, which means that the space_info can hand out reservations for space that it doesn't actually have, and we can run out of data space. This is also a problem if you are using space caching since we don't ever calculate bytes_super for the block groups. So instead everytime we read a block group call exclude_super_stripes, which calculates the bytes_super for the block group so it can be left out of the space_info. Then whenever caching completes we just call free_excluded_extents so that the super excluded extents are freed up. Also if we are unmounting and we hit any block groups that haven't been cached we still need to call free_excluded_extents to make sure things are cleaned up properly.

| * | | | Btrfs: make sure search_bitmap finds something in remove_from_bitmapJosef Bacik2011-02-061-0/+1

The problem is if that free space spans bitmaps we would not find the space since we're looking for too many bytes. So make sure the amount of bytes we search for is limited to either the number of bytes we want, or the number of bytes left in the bitmap. This was tested by a user who was hitting the BUG() after search_bitmap. With this patch he can now mount his fs.

| * | | | Btrfs: use the global block reserve if we cannot reserve spaceJosef Bacik2011-01-281-1/+27

Now normally people have called btrfs_start_transaction() with the appropriate amount of space that we need, so we just use some of that pre-reserved space and move along happily. The problem is where people use btrfs_join_transaction(), which doesn't actually reserve any space. So we try and reserve space here, but we cannot flush delalloc, so this forces us to return -ENOSPC when in reality we have plenty of space. The most common symptom is seeing a bunch of "couldn't dirty inode" messages in syslog. With xfstests 224 we end up falling back to start_transaction and then doing all the flush delalloc stuff which causes to hang for a very long time. So instead steal from the global reserve, which is what this is meant for anyway. With this patch and the other 2 I have sent xfstests 224 now passes successfully.

This causes us to starve ourselves of reservable space during the transaction which will force us to shrink delalloc bytes and commit the transaction more often than we should. So instead just add the amount of bytes we need to add to the global reserve so reserved == size, and then add the rest back into the space_info for general use.

With this patch: - To more stable Btrfs, the part that should be corrected is clarified. - The panic isn't done by the NULL pointer reference etc. (even if BUG_ON() is increased temporarily) - The error code is returned in the place where the error can be easily returned. As a long-term plan: - BUG_ON() is reduced by using the forced-readonly framework, etc. Signed-off-by: Tsutomu Itoh <t-itoh@jp.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
