This is the default + build environment for all 64-bit SLES systems. Additionally + replace the use of 'struct timespec' which uses longs internally + and is therefore different sizes on 32-bit vs 64-bit objects with + 'struct zpios_timespec_t'.a + * config/kernel.m4: Check arch/default path when detecting kernel + objects under SLES. We still preferentially use arch/arch if + available but if that fails it is acceptable to use default. + * config/kernel.m4: Remove LINUXINCLUDE from autoconf wrapper. + This breaks the 2.6.28+ kernels build system, all kernel build systems + at least post 2.6.16 will set this properly so we should not. + * lib/libspl/include/assert.h: Add ASSERTV macro to simplify removing + variables (the V in ASSERTV) which are only used in ASSERT(). + Also revert all previously modified ASSERT()s to their original + definitions and use the ASSERTV macro to handle unused variables. + * module/zpios/zpios.c: Use spl device interfaces for portability. + * scripts/common.sh: The losetup -f option is unavailable for + SLES10 use the unused_loop_device() common function. Additionally + LOSETUP is now used to portably reference the losetup binary. + * module/zfs/vdev_disk.c: Unused destroy_dirty_buffers arg removed. + * module/zfs/vdev_disk.c: BIO_RW_SYNC renamed to BIO_RW_SYNCIO. + * module/zfs/vdev_disk.c: open/close_bdev_excl() renamed to + open/close_bdev_exclusive(). + * module/zfs/vdev_disk.c: Empty write barriers are supported as of + linux 2.6.24 and are now used to implement DKIOCFLUSHWRITECACHE. + * module/zfs/vdev_disk.c: The bi_end_io API changes make partial + IO's impossible handle this case cleanly. + * module/zfs/vdev_disk.c: BIO_RW_FAILFAST replaced with + BIO_RW_FAILFAST_{DEV|_TRANSPORT|_DRIVER}, use the legacy + BIO_RW_FAILFAST flag if it exists for now. + * module/zfs/dmu_objset.c, module/zfs/spa_history.c: Excessively + large stack frames (>2048) were detected in dmu_objset_snapshot() + and spa_history_log() and were reduced by allocating from the heap. + + * Rebased to ZFS b117 from OpenSolaris: + * module/zfs/dmu.c: Update zerocopy patch to be consistent with + new flags arg passed to dmu_read(). + * module/zpios/zpios.c: Update zpios to be aware of the new flags + argument available in dmu_read(). Additionally add a zpios command + line flag to set the DMU_READ_NO_PREFETCH flag for a test. + * module/zfs/include/sys/zfs_context.h: Wrap new sysevent includes + until sysevent or something like it is implemented. + * module/zfs/zfs_ioctl.c: Wrap all the ACL interfaces with HAVE_ZPL. + They are integrated with the vfs layer which is not yet supported. + * module/zcommon/zfs_prop.c: Export new quota related symbols. + * lib/libzfs/libzfs_util.c: Increase buffer size for nvlist which + is needed for large configurations. + * lib/libzpool/kernel.c: Reimplement user kthreads based on pthread + thread specific data. This resolves previous scalabily concerns about + the cost of calling curthread which previously required a list walk. + + * Bug fixes: + * lib/libspl/include/sys/zfs_debug.h: Removed duplicate file. + * lib/libspl/include/sys/isa_defs.h: Fixed missing macro definitions + for little endian and big endian. + * cmd/zpios/zpios_main.c: Pretty-up the zpios 'make check' output. + * module/zfs/vdev_disk.c: Honor spa_mode() when opening block devs. + * module/zfs/vdev_disk.c: Initial error handling added to + vdev_disk_io_done() to revalidate the media on EIO. + * lib/libzfs/libzfs_util.c: Fix an accidentally introduced formatting + issue in zfs_nicenum() output. + 2009-07-02 Brian Behlendorf <[email protected]> * : Tag zfs-0.4.4 - Use 'git log --no-merges' for full change log. |
