wanrouter: delete now orphaned header content, files/drivers

2013-02-01T00:56:35+00:00

The wanrouter support was identified earlier as unused for years, and so the previous commit totally decoupled it from the kernel, leaving the related wanrouter files present, but totally inert. Here we take the final step in that cleanup, by doing a wholesale removal of these files. The two step process is used so that the large deletion is decoupled from the git history of files that we still care about. The drivers deleted here all were dependent on the Kconfig setting CONFIG_WAN_ROUTER_DRIVERS. A stub wanrouter.h header (kernel & uapi) are left behind so that drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that we don't accidentally break userspace that expected these defines.

net: autoconvert trivial BKL users to private mutex

2010-07-13T03:21:47+00:00

All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*/d' ${file} else sed -i 's/include.*.*$/include /g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^$static\|int\|long$/ { /^$static\|int\|long$/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/$un$*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann Cc: "David S.

[NET]: Make /proc/net per network namespace

2007-10-10T23:49:06+00:00

This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

[PATCH] mark struct file_operations const 8

2007-02-12T17:48:46+00:00

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
