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/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 736706bee3298208343a76096370e4f6a5c55915 # < make -s -j 48 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- m5272c3_defconfig # make -s -j 48 ARCH=m68k O=/kisskb/build/linus_m5272c3_defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- <stdin>:1240:2: warning: #warning syscall seccomp not implemented [-Wcpp] <stdin>:1318:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1321:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1324:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1333:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1336:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/arch/m68k/kernel/signal.c: In function 'mangle_kernel_stack': /kisskb/src/arch/m68k/kernel/signal.c:654:3: warning: variable length array 'buf' is used [-Wvla] /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/drivers/net/ethernet/freescale/fec_main.c: In function 'fec_restart': /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:912:6: warning: unused variable 'val' [-Wunused-variable] /kisskb/src/drivers/net/ethernet/freescale/fec_main.c: In function 'fec_get_mac': /kisskb/src/drivers/net/ethernet/freescale/fec_main.c:1640:28: warning: unused variable 'pdata' [-Wunused-variable] /kisskb/src/net/core/filter.c: In function 'bpf_clear_redirect_map': /kisskb/src/net/core/filter.c:3466:4: warning: value computed is not used [-Wunused-value] Completed OK # rm -rf /kisskb/build/linus_m5272c3_defconfig_m68k # Build took: 0:00:18.185185
