The\nupdates to the fdtable are done by allocating a new fdtable structure and\nsetting files-\u003efdt to point to the new structure.  The fdtable structure is\nprotected by RCU thereby allowing lock-free lookup.  For fd arrays/sets that\nare vmalloced, we use keventd to free them since RCU callbacks can\u0027t sleep.  A\nglobal list of fdtable to be freed is not scalable, so we use a per-cpu list.\nIf keventd is already handling the current cpu\u0027s work, we use a timer to defer\nqueueing of that work.\n\nSince the last publication, this patch has been re-written to avoid using\nexplicit memory barriers and use rcu_assign_pointer(), rcu_dereference()\npremitives instead.  This required that the fd information is kept in a\nseparate structure (fdtable) and updated atomically.\n\nSigned-off-by: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
