This patch changes struct file to use struct path instead of having independent pointers to struct dentry and struct vfsmount, and converts all users of f_{dentry,vfsmnt} in fs/ to use f_path.{dentry,mnt}. Additionally, it adds two #define's to make the transition easier for users of the f_dentry and f_vfsmnt. Signed-off-by: -

Moved struct path from fs/namei.c to include/linux/namei.h. This allows many places in the VFS, as well as any stackable filesystem to easily keep track of dentry-vfsmount pairs. Signed-off-by:

Introduce several fsstack_copy_* functions which allow stackable filesystems (such as eCryptfs and Unionfs) to easily copy over (currently only) inode attributes. This prevents code duplication and allows for code reuse. [akpm@osdl.org: Remove unneeded wrapper] [bunk@stusta.de: fs/stack.c should #include <linux/fs_stack.h>] Signed-off-by:

The BUG changes in -mm3 need some arch support. This patch adds the UML support needed. For the most part, it was stolen from the underlying architecture. The exception is the kernel eip < PAGE_OFFSET test, which is wrong for skas mode UMLs. Signed-off-by:

This makes x86-64 use the generic BUG machinery. The main advantage in using the generic BUG machinery for x86-64 is that the inlined overhead of BUG is just the ud2a instruction; the file+line information are no longer inlined into the instruction stream. This reduces cache pollution. Signed-off-by:

This makes i386 use the generic BUG machinery. There are no functional changes from the old i386 implementation. The main advantage in using the generic BUG machinery for i386 is that the inlined overhead of BUG is just the ud2a instruction; the file+line(+function) information are no longer inlined into the instruction stream. This reduces cache pollution, and makes disassembly work properly. Signed-off-by:

This patch adds common handling for kernel BUGs, for use by architectures as they wish. The code is derived from arch/powerpc. The advantages of having common BUG handling are: - consistent BUG reporting across architectures - shared implementation of out-of-line file/line data - implement CONFIG_DEBUG_BUGVERBOSE consistently This means that in inline impact of BUG is just the illegal instruction itself, which is an improvement for i386 and x86-64. A BUG is represented in the instruction stream as an illegal instruction, which has file/line information associated with it. This extra information is stored in the __bug_table section in the ELF file. When the kernel gets an illegal instruction, it first confirms it might possibly be from a BUG (ie, in kernel mode, the right illegal instruction). It then calls report_bug(). This searches __bug_table for a matching instruction pointer, and if found, prints the corresponding file/line information. If report_bug() determines that it wasn't a BUG which caused the trap, it returns BUG_TRAP_TYPE_NONE. Some architectures (powerpc) implement WARN using the same mechanism; if the illegal instruction was the result of a WARN, then report_bug(Q) returns CONFIG_DEBUG_BUGVERBOSE; otherwise it returns BUG_TRAP_TYPE_BUG. lib/bug.c keeps a list of loaded modules which can be searched for __bug_table entries. The architecture must call module_bug_finalize()/module_bug_cleanup() from its corresponding module_finalize/cleanup functions. Unsetting CONFIG_DEBUG_BUGVERBOSE will reduce the kernel size by some amount. At the very least, filename and line information will not be recorded for each but, but architectures may decide to store no extra information per BUG at all. Unfortunately, gcc doesn't have a general way to mark an asm() as noreturn, so architectures will generally have to include an infinite loop (or similar) in the BUG code, so that gcc knows execution won't continue beyond that point. gcc does have a __builtin_trap() operator which may be useful to achieve the same effect, unfortunately it cannot be used to actually implement the BUG itself, because there's no way to get the instruction's address for use in generating the __bug_table entry.
