Yeah, it fixes the problem for 2.6.18-rc1.
But doesn't compile for 2.6.17.4:
CC fs/splice.o fs/splice.c: In function `link_pipe': fs/splice.c:1378: warning: implicit declaration of function `mutex_lock_nested' fs/splice.c:1378: error: `I_MUTEX_PARENT' undeclared (first use in this function) fs/splice.c:1378: error: (Each undeclared identifier is reported only once fs/splice.c:1378: error: for each function it appears in.) fs/splice.c:1379: error: `I_MUTEX_CHILD' undeclared (first use in this function) make[1]: ** [fs/splice.o] Erro 1 make: ** [fs] Erro 2
Should we use the first patch for it? It does work too.
