- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

This patch modifies tmpfs to call the inode_init_security LSM hook to set up the incore inode security state for new inodes before the inode becomes accessible via the dcache. As there is no underlying storage of security xattrs in this case, it is not necessary for the hook to return the (name, value, len) triple to the tmpfs code, so this patch also modifies the SELinux hook function to correctly handle the case where the (name, value, len) pointers are NULL. The hook call is needed in tmpfs in order to support proper security labeling of tmpfs inodes (e.g. for udev with tmpfs /dev in Fedora). With this change in place, we should then be able to remove the security_inode_post_create/mkdir/... hooks safely.

Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

This patch modifies the VFS setxattr, getxattr, and listxattr code to fall back to the security module for security xattrs if the filesystem does not support xattrs natively. This allows security modules to export the incore inode security label information to userspace even if the filesystem does not provide xattr storage, and eliminates the need to individually patch various pseudo filesystem types to provide such access. The patch removes the existing xattr code from devpts and tmpfs as it is then no longer needed. The patch restructures the code flow slightly to reduce duplication between the normal path and the fallback path, but this should only have one user-visible side effect - a program may get -EACCES rather than -EOPNOTSUPP if policy denied access but the filesystem didn't support the operation anyway. Note that the post_setxattr hook call is not needed in the fallback case, as the inode_setsecurity hook call handles the incore inode security state update directly. In contrast, we do call fsnotify in both cases.

Either shmem_getpage returns a failure, or it found a page, or it was told it couldn't do any I/O. So it's useless to check nonblock in the else branch. We could add a BUG() there but I preferred to comment the offending function. This was taken out from one Ingo Molnar's old patch I'm resurrecting.

This bug could cause oopses and page state corruption, because ncpfs used the generic page-cache symlink handlign functions. But those functions only work if the page cache is guaranteed to be "stable", ie a page that was installed when the symlink walk was started has to still be installed in the page cache at the end of the walk. We could have fixed ncpfs to not use the generic helper routines, but it is in many ways much cleaner to instead improve on the symlink walking helper routines so that they don't require that absolute stability. We do this by allowing "follow_link()" to return a error-pointer as a cookie, which is fed back to the cleanup "put_link()" routine. This also simplifies NFS symlink handling.

To improve shmem scalability, we allowed tmpfs instances which don't need their blocks or inodes limited not to count them, and not to allocate any sbinfo. Which was okay when the only use for the sbinfo was accounting blocks and inodes; but since then a couple of unrelated projects extending tmpfs want to store other data in the sbinfo. Whether either extension reaches mainline is beside the point: I'm guilty of a bad design decision, and should restore sbinfo to make any such future extensions easier. So, once again allocate a shmem_sb_info for every shmem/tmpfs instance, and now let max_blocks 0 indicate unlimited blocks, and max_inodes 0 unlimited inodes. Brent Casavant verified (many months ago) that this does not perceptibly impact the scalability (since the unlimited sbinfo cacheline is repeatedly accessed but only once dirtied). And merge shmem_set_size into its sole caller shmem_remount_fs.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
