It has been requested that I try to make sure that the (one and only) dentry never has the @sys name in it. The only way we came up to do this is to extend the afs_lookup() interface to return the translated name if @sys processing was done. Does this seem appropriate?
That request came from me, as did the proposed extension to the afs_lookup interface. The rationale is that on platforms where getcwd() is implemented in user mode, it will always report the real name of the directory, rather than one involving @sys. On Linux, getcwd() is a syscall implemented in terms of the dentry cache, and getting the same behavior requires caching the real name of the inode and not an alias involving @sys. There is no such existing deterministic behavior for volumes with more than one mount point, so I am less concerned about that case (I will be sorry to lose the "you get the path you followed" behavior we currently have on Linux, but the one-alias-per-directory rule seems to tie our hands in that respect).
Obviously, I believe the afs_lookup() interface change is reasonable, provided it results in a solution to this problem short of incorporating virtually all of afs_lookup() by value into the LINUX lookup and dentry_revalidate operations.
