This is not the case with reiser3.
I am not sure which is correct. ext2 also changes mtime when it renames a directory. Also, renaming directory changes its ".." entry because on rename it may get new parent. So, probably, updating mtime on directory rename is not very incorrect. > Is this intentional ? > (it basically breaks my recover-from-snapshots script which uses the > mtime ;) > > 2 : this was posted on lkml today but it fits better here I guess : > > 2.6.12-rc1-mm4 config at > http://www-fourier.ujf-grenoble.fr/~mmarcha/config-2.6.12-rc1-mm4.gz > > running on a bi-opteron (debian-amd64), > I got some "flushing like mad" warning messages from reiser4 (which > are safe apparently). yes, if its counter does not increase endlessly. > and this soft lookup BUG caused by reiser4 I think : > Have you found a test on which this soft lockup get detected 10 times in 10 attempts? > BUG: soft lockup detected on CPU#0! > > Modules linked in: ipv6 parport_pc parport eth1394 ehci_hcd uhci_hcd > ohci1394 ieee1394 ohci_hcd usbcore snd_intel8x0 snd_ac97_codec snd_pcm > snd_timer snd snd_page_alloc i2c_amd756 i2c_amd8111 i2c_isa w83781d > i2c_sensor i2c_core e1000 > Pid: 25291, comm: pdflush Not tainted 2.6.12-rc1-mm4 > RIP: 0010:[<ffffffff8021f7de>] <ffffffff8021f7de>{protect_extent_nodes+382} > RSP: 0018:ffff81007df45678 EFLAGS: 00000202 > RAX: ffff810015c7c5e0 RBX: ffff81007c609000 RCX: ffff81001074ba60 > RDX: ffff81001074b220 RSI: ffff81001074b1c0 RDI: ffff81001074b210 > RBP: 0000002000000000 R08: ffff81007df458a0 R09: ffff810044068e14 > R10: 000000000000001c R11: ffffffff802119a0 R12: 00007fe07df455e0 > R13: ffff81007c609004 R14: ffff81007df4565c R15: 00007fe000000001 > FS: 00002aaaaadfeae0(0000) GS:ffffffff806e7840(0000) knlGS:0000000000000000 > CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b > CR2: 00002aaaaaac2000 CR3: 000000009bc83000 CR4: 00000000000006e0 > > Call Trace:<ffffffff8021f7da>{protect_extent_nodes+378} > <ffffffff8021c00e>{extent_size+30} > <ffffffff801f5df9>{txnh_get_atom+41} > <ffffffff8021ffd2>{alloc_extent+562} > <ffffffff8020a0bc>{plugin_by_unsafe_id+28} > <ffffffff80220bd1>{item_length_by_coord+17} > <ffffffff801f8a4f>{handle_pos_on_twig+351} > <ffffffff801fabc6>{flush_current_atom+2022} > <ffffffff801f7aca>{flush_some_atom+458} > <ffffffff801a2993>{generic_sync_sb_inodes+723} > <ffffffff8014cc50>{keventd_create_kthread+0} > <ffffffff80203b85>{reiser4_sync_inodes+229} > <ffffffff801a2bd9>{writeback_inodes+137} > <ffffffff8016012c>{background_writeout+124} > <ffffffff80160c10>{pdflush+0} <ffffffff80160d4c>{pdflush+316} > <ffffffff801600b0>{background_writeout+0} > <ffffffff8014cec9>{kthread+217} > <ffffffff80133160>{schedule_tail+64} <ffffffff8010f59b>{child_rip+8} > <ffffffff8014cc50>{keventd_create_kthread+0} > <ffffffff8014cdf0>{kthread+0} > <ffffffff8010f593>{child_rip+0} > > Please CC-me in answers, I am not subscribed here. > > Cheers, > Mik >
