initramfs: fix initramfs to work with hardlinked init

2009-04-13T22:04:31Z

Change cb6ff208076b5f434db1b8c983429269d719cef5 ("NOMMU: Support XIP on initramfs") seems to have broken booting from initramfs with /sbin/init being a hardlink. It seems like the logic required for XIP on nommu, i.e. ftruncate to reported cpio header file size (body_len) is broken for hardlinks, which have a reported size of 0, and the truncate thus nukes the contents of the file (in my case busybox), making boot impossible and ending with runaway loop modprobe binfmt-0000 - and of course 0000 is not a valid binary format. My fix is to only call ftruncate if size is non-zero which fixes things for me, but I'm not certain whether this will break XIP for those files on nommu systems, although I would guess not.

kbuild: make it possible for the linker to discard local symbols from vmlinux

2009-04-11T06:18:10Z

Make it possible for the linker to discard local symbols from vmlinux as they cause vmlinux to balloon when CONFIG_KALLSYMS=y and they cause dump_stack() and get_wchan() to produce useless information under some circumstances. With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause the build to supply -X to the linker to tell it to strip temporary local symbols. This doesn't seem to cause gdb any problems.

namespaces: mqueue namespace: adapt sysctl

2009-04-07T15:31:09Z

Largely inspired from ipc/ipc_sysctl.c. This patch isolates the mqueue sysctl stuff in its own file.

namespaces: mqueue ns: move mqueue_mnt into struct ipc_namespace

2009-04-07T15:31:09Z

Move mqueue vfsmount plus a few tunables into the ipc_namespace struct. The CONFIG_IPC_NS boolean and the ipc_namespace struct will serve both the posix message queue namespaces and the SYSV ipc namespaces. The sysctl code will be fixed separately in patch 3. After just this patch, making a change to posix mqueue tunables always changes the values in the initial ipc namespace. Signed-off-by: Cedric Le Goater Signed-off-by: Serge E.

Make CONFIG_SLOW_WORK an automatic rather than manual config option

2009-04-06T21:31:28Z

Make CONFIG_SLOW_WORK an automatic rather than manual config option so that people configuring their kernels don't have to make the choice. It can be selected automatically by those things that require it (such as FS-Cache). Signed-off-by: David Howells Acked-by: Jeff Garzik Acked-by: Kyle McMartin Signed-off-by: Linus Torvalds
