Hi Miao, The V3 patch on top of the next-rc fails to pass an xfstests test 13. In the btrfs link path, we need to reserve one more metadata in the trans_block_rsv for the delayed inode update (if needed) to complete.
Here's the log from the test: ------------[ cut here ]------------ kernel BUG at fs/btrfs/delayed-inode.c:1565! invalid opcode: 0000 [#2] PREEMPT SMP DEBUG_PAGEALLOC last sysfs file: /sys/module/floppy/initstate CPU 1 Modules linked in: nfsd exportfs nfs lockd fscache nfs_acl auth_rpcgss sunrpc ipv6 uinput snd_ens1371 gameport snd_rawmidi ] Pid: 6948, comm: fsstress Tainted: G D W 2.6.36-preempt+ #72 440BX Desktop Reference Platform/VMware Virtual Platform RIP: 0010:[<ffffffff8120de65>] [<ffffffff8120de65>] btrfs_delayed_update_inode+0xfd/0x101 RSP: 0018:ffff88003b073d68 EFLAGS: 00010286 RAX: 00000000ffffffe4 RBX: ffff88002a876e48 RCX: ffff88004f3702a0 RDX: 00000000000003b9 RSI: 0000000000000001 RDI: ffff88003b072000 RBP: ffff88003b073da8 R08: 0000000000018000 R09: 0000000000000000 R10: ffff88004f3703f0 R11: 09f911029d74e35b R12: ffff88006861cb90 R13: ffff88002ec91c18 R14: 0000000000018000 R15: ffff88002a876ea0 FS: 00007fcad4905720(0000) GS:ffff880005000000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f46eb380000 CR3: 00000000708b4000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process fsstress (pid: 6948, threadinfo ffff88003b072000, task ffff88004f324710) Stack: ffff88003b073d88 ffff88004f3702a0 0000000000000000 ffff88002ec91c18 <0> ffff88006861cb90 ffff880036783c18 0000000000000000 ffff88006fcaf000 <0> ffff88003b073dc8 ffffffff811d8489 ffff88002ec91c18 ffff88006861cb90 Call Trace: [<ffffffff811d8489>] btrfs_update_inode+0x17/0x44 [<ffffffff811da3e0>] btrfs_link+0xff/0x17a [<ffffffff8112300d>] vfs_link+0xda/0x144 [<ffffffff811257ac>] sys_linkat+0xc4/0x121 [<ffffffff81118925>] ? fsnotify_modify+0x66/0x6e [<ffffffff811190f8>] ? vfs_write+0xd2/0x10a [<ffffffff81125827>] sys_link+0x1e/0x20 [<ffffffff81002ddb>] system_call_fastpath+0x16/0x1b Code: f0 ff 40 60 eb 02 eb fe 4c 89 ff e8 7d 29 2b 00 31 f6 48 89 df e8 31 fb ff ff 31 c0 48 83 c4 18 5b 41 5c 41 5d 41 5e RIP [<ffffffff8120de65>] btrfs_delayed_update_inode+0xfd/0x101 RSP <ffff88003b073d68> ---[ end trace 38596ade53c80d11 ]--- -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
