  "message": "fix idr_find() locking\n\nThis is a patch that fixes the way idr_find() used to be called in ipc_lock():\nin all the paths that don\u0027t imply an update of the ipcs idr, it was called\nwithout the idr tree being locked.\n\nThe changes are:\n  . in ipc_ids, the mutex has been changed into a reader/writer semaphore.\n  . ipc_lock() now takes the mutex as a reader during the idr_find().\n  . a new routine ipc_lock_down() has been defined: it doesn\u0027t take the\n    mutex, assuming that it is being held by the caller. This is the routine\n    that is now called in all the update paths.\n\nSigned-off-by: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nAcked-by: Jarek Poplawski \u003cjarkao2@o2.pl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
