posix: Implement a janitor thread to close fd
Problem: In the commit fb20713b380e1df8d7f9e9df96563be2f9144fd6 we use syntask to close fd but we have found the patch is reducing the performance Solution: Use janitor thread to close fd's and save the pfd ctx into ctx janitor list and also save the posix_xlator into pfd object to avoid the race condition during cleanup in brick_mux environment Change-Id: Ifb3d18a854b267333a3a9e39845bfefb83fbc092 Fixes: #1396 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
