static struct hlist_head *inode_hashtable __read_mostly;
what is the use of __read_mostly ?
I did not find any detailed documentation for this
on GCC website , Is it GCC optimization feature ?
Only thing I learnt is that It is used in SMP system
in that , given only reads , each processor can cache
copy of these kind of variables however if a write occurs,
one processor assumes ownership of
that general memory
area and this is a very expensive operation ..... ( cache bouncing ...)
??
Is this the correct use of these variables ???
