    [PATCH] `event' removal: other filesystems · 9448b90c

    Patch from Manfred Spraul
    
    Several filesystems compare f_version and i_version to validate
    directory positions in readdir(): The directory position is revalidated
    if i_version is not equal f_version.  Operations that could invalidate
    the cached position set i_version or f_version to '++event', event is a
    global variable.  Global uniqueness is not needed, 'i_version++' and
    'f_version=0' is sufficient to guarantee that the next readdir() will
    revalidate the directory position, and that avoids the need for an ugly
    global variable.
    
    The attached patch converts all filesystems except ext2, which was
    converted with a seperate patch.
