SUNRPC: cleanup ida information when removing sunrpc module
After removing sunrpc module, I get many kmemleak information as, unreferenced object 0xffff88003316b1e0 (size 544): comm "gssproxy", pid 2148, jiffies 4294794465 (age 4200.081s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<ffffffffb0cfb58a>] kmemleak_alloc+0x4a/0xa0 [<ffffffffb03507fe>] kmem_cache_alloc+0x15e/0x1f0 [<ffffffffb0639baa>] ida_pre_get+0xaa/0x150 [<ffffffffb0639cfd>] ida_simple_get+0xad/0x180 [<ffffffffc06054fb>] nlmsvc_lookup_host+0x4ab/0x7f0 [lockd] [<ffffffffc0605e1d>] lockd+0x4d/0x270 [lockd] [<ffffffffc06061e5>] param_set_timeout+0x55/0x100 [lockd] [<ffffffffc06cba24>] svc_defer+0x114/0x3f0 [sunrpc] [<ffffffffc06cbbe7>] svc_defer+0x2d7/0x3f0 [sunrpc] [<ffffffffc06c71da>] rpc_show_info+0x8a/0x110 [sunrpc] [<ffffffffb044a33f>] proc_reg_write+0x7f/0xc0 [<ffffffffb038e41f>] __vfs_write+0xdf/0x3c0 [<ffffffffb0390f1f>] vfs_write+0xef/0x240 [<ffffffffb0392fbd>] SyS_write+0xad/0x130 [<ffffffffb0d06c37>] entry_SYSCALL_64_fastpath+0x1a/0xa9 [<ffffffffffffffff>] 0xffffffffffffffff I found, the ida information (dynamic memory) isn't cleanup.
