If one\nthread in a task is flushing the GRU and another thread destroys the GRU\ncontext, there is the potential to access a table after it has been freed.\n\nCopy the gms pointer to a local variable before unlocking the gts table.\nNote that no refcnt is needed for the gms - the reference is held\nindirectly by the task\u0027s mm_struct.\n\nSigned-off-by: Jack Steiner \u003csteiner@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
