  • efc557570   [XFS] avoid memory allocations in xfs_fs_vcmn_err ... Browse Code »

    xfs_fs_vcmn_err can be called under a spinlock, but does a sleeping memory
    allocation to create buffer for it's internal sprintf. Fortunately it's
    the only caller of icmn_err, so we can merge the two and have one single
    static buffer and spinlock protecting it. While we're at it make sure
    we proper __attribute__ format annotations so that the compiler can detect
    mismatched format strings.

  • 1550d0b0b   [XFS] kill INDUCE_IO_ERROR ... Browse Code »

    All the error injection is already enabled through ifdef DEBUG, so kill
    the never set second cpp symbol to activate it without the rest of the
    debugging infrastructure.

  • 9f8868ffb   [XFS] streamline init/exit path ... Browse Code »

    Currently the xfs module init/exit code is a mess. It's farmed out over a
    lot of function with very little error checking. This patch makes sure we
    propagate all initialization failures properly and clean up after them.
    Various runtime initializations are replaced with compile-time
    initializations where possible to make this easier. The exit path is
    similarly consolidated.

    There's now split out function to create/destroy the kmem zones and
    alloc/free the trace buffers. I've also changed the ktrace allocations to
    KM_MAYFAIL and handled errors resulting from that.

    And yes, we really should replace the XFS_*_TRACE ifdefs with a single
    XFS_TRACE..

  • 0ce4cfd4f   [XFS] kill the vfs_fsid and vfs_altfsid members in struct bhv_vfs ... Browse Code »

    vfs_altfsid was just a pointer to mp->m_fixedfsid so we can trivially
    replace it with the latter. vfs_fsid also was identical to m_fixedfsid
    through rather obfuscated ways so we can kill it as well and simply its
    only user.
