Currently, the AFS_MOUNT_AFS #define is used to mean two completely different things: - The string "afs", corresponding to the first argument to mount(2) on many platforms and some related calls inside libafs (e.g. getnewvnode() on FBSD). - An integer identifying the AFS filesystem (e.g. gfsadd() on AIX). Depending on the platform and the build context (UKERNEL vs KERNEL), AFS_MOUNT_AFS gets defined to one of those two things. This is very confusing, and has led to mistakes in the past, such as those fixed in commit 446457a1 (afs: Set AFS_VFSFSID to a numerical value). To avoid such confusion, get rid of AFS_MOUNT_AFS completely, and replace it with two new symbols: - AFS_MOUNT_STR, the string "afs". - AFS_FSNO, the integer given to gfsadd() et al. When AFS_MOUNT_AFS is split this way, AFS_MOUNT_STR then is always defined to the same value, so remove it from the param.h files for our platforms. Instead, define it in afs.h for libafs use, and in afsd_kernel.c (the only place outside of src/afs that uses it). Also remove the logic for conditionally defining MOUNT_AFS from the param.h files, moving the logic to the same locations as AFS_MOUNT_STR. Note that this commit removes the numeric definition for AFS_MOUNT_AFS in param.sgi_65.h (aka AFS_FSNO). We never actually used this value, since AFS_FSNO is not used on IRIX; instead, we tend to use the 'afs_fstype' global instead of a constant number.

AFS is a distributed file system that enables users to share and access all of the files stored in a network of computers as easily as they access the files stored on their local machines. The file system is called distributed for this exact reason: files can reside on many different machines, but are available to users on every machine. OpenAFS 1.0 was originally released by IBM under the terms of the IBM Public License 1.0 (IPL10). For details on IPL10 see the LICENSE file in this directory. The current OpenAFS distribution is licensed under a combination of the IPL10 and many other licenses as granted by the relevant copyright holders. The LICENSE file in this directory contains more details, thought it is not a comprehensive statement. See INSTALL for information about building and installing OpenAFS on various platforms. See CODING for developer information and guidelines. See NEWS for recent changes to OpenAFS.
