Change subject: Wakeup LRU thread if fds_hard_limit/fds_hiwat reached
......................................................................
Wakeup LRU thread if fds_hard_limit/fds_hiwat reached
Currently we increment/decrement the FD count after a
file is opened/closed, but before opening a file there
is NO check for the current FD count to compare it
against the "lru_state.fds_hard_limit" or
"lru_state.fds_hiwat" (FD high water mark).
With this we can run out of FDs if
"number of FDs opened" > "FD limit" within the
LRU_Run_Interval (default 90 seconds),
To fix this we now call "mdcache_lru_fds_available()"
before opening a file, so that if the fds_hard_limit/fds_hiwat
is reached we wake up the LRU thread to free some FDs
to make space for new FDs.
