in [Kernel]

Prev: linux-next: Tree for June 18 (XEN build error)
Next: [PATCH 2/3 2.6.27] open-iscsi - add support for pdu digest offload and payload direct-placement
From: Arjan van de Ven on 19 Jun 2008 01:40 In the kerneloops.org stats, a new oops is rapidly climbing the charts. The oops is a page fault in the ext3 "do_slit" function, and the first report of it was with 2.6.26-rc6-git3. It happens with various applications; the backtraces are at: http://www.kerneloops.org/search.php?search=do_split but are generally of this pattern: *do_split ext3_add_entry ext3_rename vfs_rename .... <various paths into vfs_rename> ... or *do_split ? add_dirent_to_buf ext3_add_entry ext3_new_inode ext3_add_nondir ext3_create vfs_create ..... did we change anything in ext3 this cycle? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I'm not seeing anything relevant, but I'm adding Al to the cc in, since the r/o bind mounts did change fs/namei.c and vfs_create/mkdir in particular. Not that I see why that would trigger either, but the changes to fs/ext3/namei.c seem to be even _less_ interesting than that. One thing I note is that all the oopses seem to be i686 - are there that few x86-64 fc10 users (I'd have assumed that 64-bit is starting to be the norm for people who live on the edge, but perhaps I'm just out of touch)? Or could this perhaps be an indication that it is specific to i686 some way (eg a compiler issue?)
