We have a persistent dribble of reports of this BUG triggering. Its extended diagnostics were recently made conditional on CONFIG_DEBUG_VM, which was a bad idea - we want to know about it. Signed-off-by:

Current error behaviour for ext2 and ext3 filesystems does not fully correspond to the documentation and should be fixed. According to man 8 mount, ext2 and ext3 file systems allow to set one of 3 different on-errors behaviours: ---- start of quote man 8 mount ---- errors=continue / errors=remount-ro / errors=panic Define the behaviour when an error is encountered. (Either ignore errors and just mark the file system erroneous and continue, or remount the file system read-only, or panic and halt the system.) The default is set in the filesystem superblock, and can be changed using tune2fs(8). ---- end of quote ---- However EXT3_ERRORS_CONTINUE is not read from the superblock, and thus ERRORS_CONT is not saved on the sbi->s_mount_opt. It leads to the incorrect handle of errors on ext3. Then we've checked corresponding code in ext2 and discovered that it is buggy as well: - EXT2_ERRORS_CONTINUE is not read from the superblock (the same); - parse_option() does not clean the alternative values and thus something like (ERRORS_CONT|ERRORS_RO) can be set; - if options are omitted, parse_option() does not set any of these options. Therefore it is possible to set any combination of these options on the ext2: - none of them may be set: EXT2_ERRORS_CONTINUE on superblock / empty mount options; - any of them may be set using mount options; - 2 any options may be set: by using EXT2_ERRORS_RO/EXT2_ERRORS_PANIC on the superblock and other value in mount options; - and finally all three options may be set by adding third option in remount. Currently ext2 uses these values only in ext2_error() and it is not leading to any noticeable troubles. However somebody may be discouraged when he will try to workaround EXT2_ERRORS_PANIC on the superblock by using errors=continue in mount options. This patch: EXT4_ERRORS_CONTINUE should be taken from the superblock as default value for error behaviour. Signed-off-by:Dmitry Mishin <dim@openvz.org> Acked-by:

I assume this means "logical sb block". So call it that. I still don't understand the name though. A block is a block. What's different about this one? Cc: <linux-ext4@vger.kernel.org> Signed-off-by:

With CONFIG_LBD=n, sector_div() expands to a plain old divide. But ext4 is _not_ passing in a sector_t as the first argument, so... fs/built-in.o: In function `ext4_get_group_no_and_offset': fs/ext4/balloc.c:39: undefined reference to `__umoddi3' fs/ext4/balloc.c:41: undefined reference to `__udivdi3' fs/built-in.o: In function `find_group_orlov': fs/ext4/ialloc.c:278: undefined reference to `__udivdi3' fs/built-in.o: In function `ext4_fill_super': fs/ext4/super.c:1488: undefined reference to `__udivdi3' fs/ext4/super.c:1488: undefined reference to `__umoddi3' fs/ext4/super.c:1594: undefined reference to `__udivdi3' fs/ext4/super.c:1601: undefined reference to `__umoddi3' Fix that up by calling do_div() directly. Also cast the arg to u64. do_div() is only defined on u64, and ext4_fsblk_t is supposed to be opaque. Note especially the changes to find_group_orlov(). It was attempting to do do_div(int, unsigned long long); which is royally screwed up. Switched it to plain old divide. Cc: <linux-ext4@vger.kernel.org> Signed-off-by:

Mingming Cao authored
Previously when in-kernel ext4 block type is sector_t, it's only 4 bits long under some 32bit arch (when CONFIG_LBD is not on). So we need to check the size of sector_t before we read 48bit long on-disk blocks to in-kernel blocks. These checks are unnecessary now as we changed the in-kernel blocks to unsigned longlong.

As we are planning to support 48-bit block numbers for ext4, we need to support 48-bit block numbers for extended attributes. In the short term, we can do this by reuse (on-disk) 16-bit padding (linux2.i_pad1 currently used only by "hurd") as high order bits for xattr. This patch basically does that. Signed-off-by:

commit fe1668ae causes kernel to oops with libhugetlbfs test suite. The problem is that hugetlb pages can be shared by multiple mappings. Multiple threads can fight over page->lru in the unmap path and bad things happen. We now serialize __unmap_hugepage_range to void concurrent linked list manipulation. Such serialization is also needed for shared page table page on hugetlb area. This patch will fixed the bug and also serve as a prepatch for shared page table. Signed-off-by:

Mel Gorman authored
Arch-independent zone-sizing is using indices instead of symbolic names to offset within an array related to zones (max_zone_pfns). The unintended impact is that ZONE_DMA and ZONE_NORMAL is initialised on powerpc instead of ZONE_DMA and ZONE_HIGHMEM when CONFIG_HIGHMEM is set. As a result, the the machine fails to boot but will boot with CONFIG_HIGHMEM turned off. The following patch properly initialises the max_zone_pfns[] array and uses symbolic names instead of indices in each architecture using arch-independent zone-sizing. Two users have successfully booted their powerpcs with it (one an ibook G4). It has also been boot tested on x86, x86_64, ppc64 and ia64. Please merge for 2.6.19-rc2. Credit to Benjamin Herrenschmidt for identifying the bug and rolling the first fix. Additional credit to Johannes Berg and Andreas Schwab for reporting the problem and testing on powerpc.
