looks like some slow_path issue, but I'm not familiar with these kernel details. The share I'm mounting is a Windows 2003 system. It is now successfully mounted on a quite old 2.6.19-gentoo-r5 kernel, but cannot be mounted under a recent 2.6.29-gentoo-r5. Any help is appreciated. Gerhard
Am I really the only one to encounter this problem ? Any hints on why this slow_path issues taints my kernel ? I'm not sure, If this is the right place to ask, but also the kernel mailing list wasn't answering my post.
OK, solved this. Had to emerge mount-cifs and after that I could mount the share. Interesting, that mounting worked under a 2.6.19 kernel, but does'nt work under a recent kernel without using mount.cifs.
Sorry, have to reopen this. Mounting does sometimes work and most of the time not (producing the above error message). Reexporting is unfortunately no supported even when using the EXPERIMENTAL flag in the cifs module option :-(
Just to be clear, is this still an issue? Your post on lkml seems to say otherwise. http://lkml.indiana.edu/hypermail/linux/kernel/0907.2/02231.html
fat fingered that one, taking back bug
