Hi Boaz,

I think best if we can avoid having a --linux-- os.c file. If not, at 
least avoid adding one-hop for fast-path calls such as sync_file_range 
(e.g in this case under linux let it be inline as it used to be). Also, 
I wasn't sure where the patch to bs_aio.c from the previous post (11/14) 
landed in this sequence.


Or.
