But we haven't supported that in a long time, and these # days the 'type' argument is a purely historical artifact. # # A discussion about extending 'user_access_begin()' to do the range # checking resulted this patch, because there is no way we're going to # move the old VERIFY_xyz interface to that model. And it's best done at # the end of the merge window when I've done most of my merges, so let's # just get this done once and for all. # # This patch was mostly done with a sed-script, with manual fix-ups for # the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. # # There were a couple of notable cases: # # - csky still had the old "verify_area()" name as an alias. # # - the iter_iov code had magical hardcoded knowledge of the actual # values of VERIFY_{READ,WRITE} (not that they mattered, since nothing # really used it) # # - microblaze used the type argument for a debug printout # # but other than those oddities this should be a total no-op patch. # # I tried to fix up all architectures, did fairly extensive grepping for # access_ok() uses, and the changes are trivial, but I may have missed # something. Any missed conversion should be trivially fixable, though. # # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-ld --version # < git log --format=%s --max-count=1 96d4f267e40f9509e8a66e2b39e8b95655617693 # < make -s -j 8 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allmodconfig # make -s -j 8 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- /kisskb/src/fs/cifs/cifssmb.c: In function '__cifs_reconnect_tcon': /kisskb/src/fs/cifs/cifssmb.c:186:1: warning: the frame size of 1320 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/fs/cifs/smb2pdu.c: In function '__smb2_reconnect': /kisskb/src/fs/cifs/smb2pdu.c:220:1: warning: the frame size of 1320 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
