CIFSTCon fix
------- Comment From vinaysridhar.com 2009-04-01 02:33 EDT------- Red Hat, Will this fix be considered for f11? btw, upstream commit: http://lkml.org/lkml/2009/3/31/490 The patch is already in 2.6.29 and has been proposed for stable. F11 will likely release with a 2.6.29 kernel so this should make it. I'll leave it open for now and we can close it once F10 has a kernel with this patch. The fix is in 2.6.30 and is going into 2.6.29.1. F11 will have at least that kernel and possibly a later one. F10 will be getting that kernel too. Fix is now upstream. Closing bug with resolution of RAWHIDE. ------- Comment From vinaysridhar.com 2009-04-05 23:20 EDT------- Closing on IBM side ------- Comment From pavan.naregundi.com 2009-04-09 03:27 EDT------- I still geting the call trace in F11beta # uname -a Linux mjs22lp1 2.6.29-0.258.2.3.rc8.git2.fc11.ppc64 #1 SMP Tue Mar 24 18:41:15 EDT 2009 ppc64 ppc64 ppc64 GNU/Linux # mount.cifs //9.126.89.222/SAMBA /SAMBA1/ -o username=root Password: mount error(2): No such file or directory Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) [root@mjs22lp1 /]# dmesg CIFS VFS: cifs_read_super: get root inode failed ============================================================================= BUG kmalloc-8 (Not tainted): Redzone overwritten ----------------------------------------------------------------------------- INFO: 0xc00000005aedf378-0xc00000005aedf37c.
