It's an entirely # historical artifact, and long long long ago used to actually read the # segment selector valueof '%ds' on x86. # # Which in the kernel is always KERNEL_DS. # # Inspired by a patch from Jann Horn that just did this for a very small # subset of users (the ones in fs/), along with Al who suggested a script. # I then just took it to the logical extreme and removed all the remaining # gunk. # # Roughly scripted with # # git grep -l '(get_ds())' -- :^tools/ \| xargs sed -i 's/(get_ds())/(KERNEL_DS)/' # git grep -lw 'get_ds' -- :^tools/ \| xargs sed -i '/^#define get_ds()/d' # # plus manual fixups to remove a few unusual usage patterns, the couple of # inline function cases and to fix up a comment that had become stale. # # The 'get_ds()' function remains in an x86 kvm selftest, since in user # space it actually does something relevant. # # Inspired-by: Jann Horn <jannh@google.com> # Inspired-by: Al Viro <viro@zeniv.linux.org.uk> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 736706bee3298208343a76096370e4f6a5c55915 # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_lubbock_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- lubbock_defconfig # make -s -j 48 ARCH=arm O=/kisskb/build/linus_lubbock_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here /kisskb/src/net/ipv4/ip_output.c: In function '__ip_append_data': /kisskb/src/include/linux/skbuff.h:1338:6: warning: 'extra_uref' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/ipv4/ip_output.c:885:14: note: 'extra_uref' was declared here Completed OK # rm -rf /kisskb/build/linus_lubbock_defconfig_arm # Build took: 0:00:35.692764
