2011-01-10ext4: fix 32bit overflow in ext4_ext_find_goal()Kazuya Mio1-4/+26
ext4_ext_find_goal() returns an ideal physical block number that the block allocator tries to allocate first. However, if a required file offset is smaller than the existing extent's one, ext4_ext_find_goal() returns a wrong block number because it may overflow at "block - le32_to_cpu(ex->ee_block)". This patch fixes the problem. ext4_ext_find_goal() will also return a wrong block number in case a file offset of the existing extent is too big. In this case, the ideal physical block number is fixed in ext4_mb_initialize_context(), so it's no problem. reproduce: # dd if=/dev/zero of=/mnt/mp1/tmp bs=127M count=1 oflag=sync # dd if=/dev/zero of=/mnt/mp1/file bs=512K count=1 seek=1 oflag=sync # filefrag -v /mnt/mp1/file Filesystem type is: ef53 File size of /mnt/mp1/file is 1048576 (256 blocks, blocksize 4096) ext logical physical expected length flags 0 128 67456 128 eof /mnt/mp1/file: 2 extents found # rm -rf /mnt/mp1/tmp # echo $((512*4096)) > /sys/fs/ext4/loop0/mb_stream_req # dd if=/dev/zero of=/mnt/mp1/file bs=512K count=1 oflag=sync conv=notrunc result (linux-2.6.37-rc2 + ext4 patch queue): # filefrag -v /mnt/mp1/file Filesystem type is: ef53 File size of /mnt/mp1/file is 1048576 (256 blocks, blocksize 4096) ext logical physical expected length flags 0 0 33280 128 1 128 67456 33407 128 eof /mnt/mp1/file: 2 extents found result(apply this patch): # filefrag -v /mnt/mp1/file Filesystem type is: ef53 File size of /mnt/mp1/file is 1048576 (256 blocks, blocksize 4096) ext logical physical expected length flags 0 0 66560 128 1 128 67456 66687 128 eof /mnt/mp1/file: 2 extents found Signed-off-by: Kazuya Mio <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>

2011-01-10ext4: ext4_ext_migrate should use NULL not 0Eric Paris1-1/+1
ext4_ext_migrate() calls ext4_new_inode() and passes 0 instead of a pointer to a struct qstr. This patch uses NULL, to make it obvious to the caller that this was a pointer. Signed-off-by: Eric Paris <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>

2011-01-10ext4: remove warning message from ext4_issue_discard helperLukas Czerner1-12/+10
ext4_issue_discard is supposed to be helper for calling discard, however in case that underlying device does not support discard it prints out the warning message and clears the DISCARD t_mount_opt flag. Since it can be (and is) used by others, it should not do anything and let the caller to handle the error case. This commit removes warning message and flag setting from ext4_issue_discard and use it just in place where it is really needed (release_blocks_on_commit). FITRIM ioctl should not set any flags nor it should print out warning messages, so get rid of the warning as well. Signed-off-by: Lukas Czerner <[email protected]>
2011-01-10ext4: fix possible overflow in ext4_trim_fs()Lukas Czerner1-0/+6
When determining last group through ext4_get_group_no_and_offset() the result may be wrong in cases when range->start and range-len are too big, because it may overflow when summing up those two numbers. Fix that by checking range->len and limit its value to ext4_blocks_count(). This commit was tested by myself with expected result. Signed-off-by: Lukas Czerner <[email protected]>

Currently the x86 platform devices are not consistent about selecting or depending on the LEDs Kconfig variables, and this inconsistency leads to Kconfig getting upset and refusing to offer LEDs (even on non-x86 platforms): drivers/platform/x86/Kconfig:422:error: recursive dependency detected! drivers/platform/x86/Kconfig:422: symbol EEEPC_WMI depends on ACPI_WMI drivers/platform/x86/Kconfig:438: symbol ACPI_WMI is selected by ACER_WMI drivers/platform/x86/Kconfig:18: symbol ACER_WMI depends on LEDS_CLASS drivers/leds/Kconfig:10: symbol LEDS_CLASS is selected by EEEPC_WMI Fix this by always selecting rather than depending on the symbols as slightly more drivers use this approach already and it seems more user friendly.

2011-01-10xen: disable ACPI NUMA for PV guestsIan Campbell1-0/+9
Xen does not currently expose PV-NUMA information to PV guests. Therefore disable NUMA for the time being to prevent the kernel picking up on an host-level NUMA information which it might come across in the firmware.

2011-01-10perf stat: better error message for unsupported eventsDavid Ahern1-0/+2
For unsupported events (e.g., H/W events when running in a VM) perf stat currently fails with the error message: Error: open_counter returned with 2 (No such file or directory). /bin/dmesg may provide additional information. Fatal: Not all events could be opened. dmesg is of no help and it is not clear as to why it fails to open the counter. This patch changes the error message to Error: cache-misses event is not supported. Fatal: Not all events could be opened.

2011-01-10Blackfin: encode cpu-rev into uImage nameMike Frysinger2-3/+6
Encoding the cpu family name apparently confuses people when they try to boot an image on a sub-variant, so encode the specific cpu name and the silicon rev instead. Signed-off-by: Mike Frysinger <[email protected]>
2011-01-10Blackfin: bf54x: don't ack GPIO ints when unmasking themMike Frysinger1-1/+0
When unmasking a GPIO interrupt on a BF54x part, the code will implicitly ack any pending interrupts. This is not what unmasking should do and can cause people to miss interrupts from their devices, so punt the code.
