Print out the name of the file that triggers the cookie loop message to make it slightly easier to track down the cause. Signed-off-by:

Trond Myklebust authored
If the directory contents change, then we have to accept that the file->f_pos value may shrink if we do a 'search-by-cookie'. In that case, we should turn off the loop detection and let the NFS client try to recover. The patch also fixes a second loop detection bug by ensuring that after turning on the ctx->duped flag, we read at least one new cookie into ctx->dir_cookie before attempting to match with ctx->dup_cookie.

nfs_mark_return_delegation() is usually called without any locking, and so it is not safe to dereference delegation->inode. Since the inode is only used to discover the nfs_client anyway, it makes more sense to have the callers pass a valid pointer to the nfs_server as a parameter. Reported-by:

If the task that initiated the sillyrename ends up being killed by a fatal signal, then it will eventually return back to userspace and end up releasing the i_mutex. d_move however needs to be done while holding the i_mutex. Instead of using d_move here, just unhash the old and new dentries to prevent them from being found by lookups. With this change though, the dentries are now incorrect post-rename and do not reflect the actual name of the file on the server. I'm proceeding under the assumption that since they are unhashed that this isn't really a problem. In order for the sillydelete to still work though, the dname must be copied earlier when setting up the sillydelete info, and the name must be recopied if the sillydelete info has to be moved to a new dentry.

The commit f02e8a65 sorts symbols placing each of them in its own elf section. The sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux (already linked) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet. That breaks modpost that can't detect license properly for modules. This patch makes modpost aware of the new exported symbols structure. Thanks to Arnaud Lacombe <lacombar@gmail.com> and Anders Kaseorg <andersk@ksplice.com> for providing useful suggestions about code. This work was supported by a hardware donation from the CE Linux Forum. Reported-by:

Userspace wants to manage module parameters with udev rules. This currently only works for loaded modules, but not for built-in ones. To allow access to the built-in modules we need to re-trigger all module load events that happened before any userspace was running. We already do the same thing for all devices, subsystems(buses) and drivers. This adds the currently missing /sys/module/<name>/uevent files to all module entries.
