#     fs/dcache: Track & report number of negative dentries
#     
#     The current dentry number tracking code doesn't distinguish between
#     positive & negative dentries.  It just reports the total number of
#     dentries in the LRU lists.
#     
#     As excessive number of negative dentries can have an impact on system
#     performance, it will be wise to track the number of positive and
#     negative dentries separately.
#     
#     This patch adds tracking for the total number of negative dentries in
#     the system LRU lists and reports it in the 5th field in the
#     /proc/sys/fs/dentry-state file.  The number, however, does not include
#     negative dentries that are in flight but not in the LRU yet as well as
#     those in the shrinker lists which are on the way out anyway.
#     
#     The number of positive dentries in the LRU lists can be roughly found by
#     subtracting the number of negative dentries from the unused count.
#     
#     Matthew Wilcox had confirmed that since the introduction of the
#     dentry_stat structure in 2.1.60, the dummy array was there, probably for
#     future extension.  They were not replacements of pre-existing fields.
#     So no sane applications that read the value of /proc/sys/fs/dentry-state
#     will do dummy thing if the last 2 fields of the sysctl parameter are not
#     zero.  IOW, it will be safe to use one of the dummy array entry for
#     negative dentry count.
