    Fix build errors due to CONFIG_BRANCH_TRACER=y

    torvalds authored
    The code that enables branch tracing for all (non-constant) branches
    plays games with the preprocessor and #define's the C 'if ()' construct
    to do tracing.
    
    That's all fine, but it fails for some unusual but valid C code that is
    sometimes used in macros, notably by the intel-iommu code:
    
    	if (i=drhd->iommu, drhd->ignored) ..
    
    because now the preprocessor complains about multiple arguments to the
    'if' macro.
    
    So make the macro expansion of this particularly horrid trick use
    varargs, and handle the case of comma-expressions in if-statements.  Use
    another macro to do it cleanly in just one place.
    
    This replaces a patch by David (and acked by Steven) that did this all
    inside that one already-too-horrid macro.

    splice: fix deadlock in splicing to file

    Miklos Szeredi authored torvalds committed
    There's a possible deadlock in generic_file_splice_write(),
    splice_from_pipe() and ocfs2_file_splice_write():
    
     - task A calls generic_file_splice_write()
     - this calls inode_double_lock(), which locks i_mutex on both
       pipe->inode and target inode
     - ordering depends on inode pointers, can happen that pipe->inode is
       locked first
     - __splice_from_pipe() needs more data, calls pipe_wait()
     - this releases lock on pipe->inode, goes to interruptible sleep
     - task B calls generic_file_splice_write(), similarly to the first
     - this locks pipe->inode, then tries to lock inode, but that is
       already held by task A
     - task A is interrupted, it tries to lock pipe->inode, but fails, as
       it is already held by task B
     - ABBA deadlock
    
    Fix this by explicitly ordering locks: the outer lock must be on
    target inode and the inner lock (which is later unlocked and relocked)
    must be on pipe->inode.  This is OK, pipe inodes and target inodes
    form two nonoverlapping sets, generic_file_splice_write() and friends
    are not called with a target which is a pipe.

    nilfs2: support nanosecond timestamp

    konis authored torvalds committed
    After a review of user's feedback for finding out other compatibility
    issues, I found nilfs improperly initializes timestamps in inode;
    CURRENT_TIME was used there instead of CURRENT_TIME_SEC even though nilfs
    didn't have nanosecond timestamps on disk.  A few users gave us the report
    that the tar program sometimes failed to expand symbolic links on nilfs,
    and it turned out to be the cause.
    
    Instead of applying the above displacement, I've decided to support
    nanosecond timestamps on this occation.  Fortunetaly, a needless 64-bit
    field was in the nilfs_inode struct, and I found it's available for this
    purpose without impact for the users.
    
    So, this will do the enhancement and resolve the tar problem.

    nilfs2: introduce secondary super block

    konis authored torvalds committed
    The former versions didn't have extra super blocks.  This improves the
    weak point by introducing another super block at unused region in tail of
    the partition.
    
    This doesn't break disk format compatibility; older versions just ingore
    the secondary super block, and new versions just recover it if it doesn't
    exist.  The partition created by an old mkfs may not have unused region,
    but in that case, the secondary super block will not be added.
    
    This doesn't make more redundant copies of the super block; it is a future
    work.

    nilfs2: simplify handling of active state of segments

    konis authored torvalds committed
    will reduce some lines of segment constructor.  Previously, the state was
    complexly controlled through a list of segments in order to keep
    consistency in meta data of usage state of segments.  Instead, this
    presents ``calculated'' active flags to userland cleaner program and stop
    maintaining its real flag on disk.
    
    Only by this fake flag, the cleaner cannot exactly know if each segment is
    reclaimable or not.  However, the recent extension of nilfs_sustat ioctl
    struct (nilfs2-extend-nilfs_sustat-ioctl-struct.patch) can prevent the
    cleaner from reclaiming in-use segment wrongly.
    
    So, now I can apply this for simplification.

    nilfs2: mark minor flag for checkpoint created by internal operation

    konis authored torvalds committed
    Nilfs creates checkpoints even for garbage collection or metadata updates
    such as checkpoint mode change.  So, user often sees checkpoints created
    only by such internal operations.
    
    This is inconvenient in some situations.  For example, application that
    monitors checkpoints and changes them to snapshots, will fall into an
    infinite loop because it cannot distinguish internally created
    checkpoints.
    
    This patch solves this sort of problem by adding a flag to checkpoint for
    identification.

    nilfs2: clean up sketch file

    konis authored torvalds committed
    The sketch file is a file to mark checkpoints with user data.  It was
    experimentally introduced in the original implementation, and now
    obsolete.  The file was handled differently with regular files; the file
    size got truncated when a checkpoint was created.
    
    This stops the special treatment and will treat it as a regular file.
    Most users are not affected because mkfs.nilfs2 no longer makes this file.

    nilfs2: replace BUG_ON and BUG calls triggerable from ioctl

    konis authored torvalds committed
    Pekka Enberg advised me:
    > It would be nice if BUG(), BUG_ON(), and panic() calls would be
    > converted to proper error handling using WARN_ON() calls. The BUG()
    > call in nilfs_cpfile_delete_checkpoints(), for example, looks to be
    > triggerable from user-space via the ioctl() system call.
    
    This will follow the comment and keep them to a minimum.

    nilfs2: extend nilfs_sustat ioctl struct

    konis authored torvalds committed
    This adds a new argument to the nilfs_sustat structure.
    
    The extended field allows to delete volatile active state of segments,
    which was needed to protect freshly-created segments from garbage
    collection but has confused code dealing with segments.  This
    extension alleviates the mess and gives room for further
    simplifications.
    
    The volatile active flag is not persistent, so it's eliminable on this
    occasion without affecting compatibility other than the ioctl change.

    nilfs2: use unlocked_ioctl

    konis authored torvalds committed
    Pekka Enberg suggested converting ->ioctl operations to use
    ->unlocked_ioctl to avoid BKL.
    
    The conversion was verified to be safe, so I will take it on this
    occasion.
