Hello, I am working on getting Unionfs to work on 2.6.18-rc2 and while it compiles I am getting "Unknown symbol in module". The reason this is occurring is that the export for tasklist_lock has been deprecated. If a driver has no business taking this lock as the git comment says then perhaps I was not doing something properly in the first place. So here is the situation. In Unionfs there are two instances where we need to drop/grant privileges to a specific operation. In this case we need to be able to delete a file on the file system, however it is possible that it was created by a different user with a umask that does not allow us to delete it. We were grabbing a write_lock on tasklist_lock and then calling security_capget and security_capset_set. This wasn't completely correct to begin with since the references to this in the kernel specify that locks are held on task_capability_lock and tasklist_lock while they perform the operation. Is there a new method to drop/grant privileges now that this lock is no longer visible or is this a you should try to get into the kernel situation? Even if it is the latter of the two it doesn't help if you want to load Unionfs as a module instead of compiling it into the kernel. -- David Quigley <dpquigl@xxxxxxxxxxxxx> - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
