Looks like it is just because of allmodconfig. Interesting fact, though: now warnings are thrown on on-disk operations, errors are on rbtree operations. --------------060400070809020403030809 Content-Type: text/plain; name="btrfs.warn" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline; filename="btrfs.warn" [ 781.230303] ------------[ cut here ]------------ [ 781.230368] WARNING: at fs/btrfs/inode.c:3117 inode_tree_add+0xd0/0x16= 2 [btrfs]() [ 781.230371] Hardware name: X51RL [ 781.230374] Modules linked in: usblp raid456 raid6_pq async_xor async_= memcpy async_tx xor snd_pcm_oss snd_mixer_oss raid1 af_packet raid0 md_mo= d ipv6 ipip tunnel4 radeon drm snd_hda_codec_si3054 snd_hda_codec_realtek= snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_timer snd soundcore sn= d_page_alloc atiixp ftdi_sio usbserial loop ati_agp agpgart p4_clockmod s= peedstep_lib 8139too mii kqemu fuse thermal thermal_sys hwmon ac battery = asus_laptop backlight led_class tun usb_storage usb_libusual dm_mod ide_g= eneric ide_gd_mod ide_cd_mod ide_core sr_mod cdrom pata_marvell ata_piix = sata_uli sata_sis pata_sis sata_via sata_nv ahci fbdev xtkbd atkbd ohci_h= cd ssb pcmcia pcmcia_core firmware_class ehci_hcd uhci_hcd usbhid hid usb= core unix btrfs zlib_deflate libcrc32c crc32c libata sd_mod scsi_mod crc_= t10dif jfs nls_base xfs exportfs ext3 jbd mbcache synaptics_i2c i2c_core = sermouse psmouse libps2 pcips2 i8042 serio evdev mousedev [ 781.230479] Pid: 25678, comm: perl Not tainted 2.6.31-rc2 #1 [ 781.230482] Call Trace: [ 781.230523] [] ? inode_tree_add+0xd0/0x162 [btrfs] [ 781.230532] [] warn_slowpath_common+0xe0/0x148 [ 781.230538] [] warn_slowpath_null+0x29/0x3a [ 781.230579] [] inode_tree_add+0xd0/0x162 [btrfs] [ 781.230621] [] btrfs_iget+0x6cb/0x6f8 [btrfs] [ 781.230627] [] ? kmap_atomic+0x22/0x32 [ 781.230669] [] btrfs_lookup_dentry+0x288/0x2d1 [btrfs] [ 781.230711] [] btrfs_lookup+0x37/0x82 [btrfs] [ 781.230728] [] do_lookup+0x153/0x2cb [ 781.230733] [] __link_path_walk+0xcf8/0xf61 [ 781.230738] [] path_walk+0xb4/0x19b [ 781.230743] [] do_path_lookup+0x4f/0x193 [ 781.230748] [] user_path_at+0x94/0xe4 [ 781.230755] [] vfs_fstatat+0x5f/0xc0 [ 781.230761] [] vfs_lstat+0x24/0x34 [ 781.230766] [] sys_lstat64+0x22/0x60 [ 781.230772] [] sysenter_do_call+0x12/0x28 [ 781.230776] ---[ end trace aefd5bf8b0fdf91e ]--- --------------060400070809020403030809--
