Alexey Dobriyan 49af7ee181 nfs: fix oops re sysctls and V4 support ... NFS unregisters sysctls only if V4 support is compiled in. However, sysctl table is not V4 specific, so unregister it always. Steps to reproduce: [build nfs.ko with CONFIG_NFS_V4=n] modrobe nfs rmmod nfs ls /proc/sys Unable to handle kernel paging request at ffffffff880661c0 RIP: [<ffffffff802af8e3>] proc_sys_readdir+0xd3/0x350 PGD 203067 PUD 207063 PMD 7e216067 PTE 0 Oops: 0000 [1] SMP CPU 1 Modules linked in: lockd nfs_acl sunrpc Pid: 3335, comm: ls Not tainted 2.6.23-rc3-bloat #2 RIP: 0010:[<ffffffff802af8e3>] [<ffffffff802af8e3>] proc_sys_readdir+0xd3/0x350 RSP: 0018:ffff81007fd93e78 EFLAGS: 00010286 RAX: ffffffff880661c0 RBX: ffffffff80466370 RCX: ffffffff880661c0 RDX: 00000000000014c0 RSI: ffff81007f3ad020 RDI: ffff81007efd8b40 RBP: 0000000000000018 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000001 R11: ffffffff802a8570 R12: ffffffff880661c0 R13: ffff81007e219640 R14: ffff81007efd8b40 R15: ffff81007ded7280 FS: 00002ba25ef03060(0000) GS:ffff81007ff81258(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: ffffffff880661c0 CR3: 000000007dfaf000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process ls (pid: 3335, threadinfo ffff81007fd92000, task ffff81007d8a0000) Stack: ffff81007f3ad150 ffffffff80283f30 ffff81007fd93f48 ffff81007efd8b40 ffff81007ee00440 0000000422222222 0000000200035593 ffffffff88037e9a 2222222222222222 ffffffff80466500 ffff81007e416400 ffff81007e219640 Call Trace: [<ffffffff80283f30>] filldir+0x0/0xf0 [<ffffffff80283f30>] filldir+0x0/0xf0 [<ffffffff802840c7>] vfs_readdir+0xa7/0xc0 [<ffffffff80284376>] sys_getdents+0x96/0xe0 [<ffffffff8020bb3e>] system_call+0x7e/0x83 Code: 41 8b 14 24 85 d2 74 dc 49 8b 44 24 08 48 85 c0 74 e7 49 3b RIP [<ffffffff802af8e3>] proc_sys_readdir+0xd3/0x350 RSP <ffff81007fd93e78> CR2: ffffffff880661c0 Kernel panic - not syncing: Fatal exception Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Acked-by: Trond Myklebust <trond.myklebust@fys.uio.no> Cc: "J.
