That avoids the races with the event you're waiting for. # # The same goes for poll/select logic: the "poll_wait()" goes first, and # then you check the things you're polling for. # # Of course, if you use locking, the ordering doesn't matter since the # lock will serialize with anything that changes the state you're looking # at. That's not the case here, though. # # So move the poll_wait() first in pipe_poll(), before you start looking # at the pipe state. # # Fixes: 8cefc107ca54 ("pipe: Use head and tail pointers for the ring, not cursor and length") # Cc: David Howells <dhowells@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 ad910e36da4ca3a1bd436989f632d062dda0c921 # < make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # yes \n \| make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- In file included from /kisskb/src/include/linux/kernel.h:15, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/ubifs/ubifs.h:16, from /kisskb/src/fs/ubifs/orphan.c:10: /kisskb/src/fs/ubifs/orphan.c: In function 'orphan_delete': /kisskb/src/fs/ubifs/debug.h:158:11: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'ino_t' {aka 'unsigned int'} [-Wformat=] pr_debug("UBIFS DBG " type " (pid %d): " fmt "\n", current->pid, \ ^~~~~~~~~~~~ /kisskb/src/include/linux/printk.h:288:21: note: in definition of macro 'pr_fmt' #define pr_fmt(fmt) fmt ^~~ /kisskb/src/include/linux/dynamic_debug.h:143:2: note: in expansion of macro '__dynamic_func_call' __dynamic_func_call(__UNIQUE_ID(ddebug), fmt, func, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/dynamic_debug.h:153:2: note: in expansion of macro '_dynamic_func_call' _dynamic_func_call(fmt, __dynamic_pr_debug, \ ^~~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/printk.h:336:2: note: in expansion of macro 'dynamic_pr_debug' dynamic_pr_debug(fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~ /kisskb/src/fs/ubifs/debug.h:158:2: note: in expansion of macro 'pr_debug' pr_debug("UBIFS DBG " type " (pid %d): " fmt "\n", current->pid, \ ^~~~~~~~ /kisskb/src/fs/ubifs/debug.h:170:29: note: in expansion of macro 'ubifs_dbg_msg' #define dbg_gen(fmt, ...) ubifs_dbg_msg("gen", fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~ /kisskb/src/fs/ubifs/orphan.c:132:3: note: in expansion of macro 'dbg_gen' dbg_gen("deleted twice ino %lu", orph->inum); ^~~~~~~ /kisskb/src/fs/ubifs/orphan.c:132:32: note: format string is defined here dbg_gen("deleted twice ino %lu", orph->inum); ~~^ %u In file included from /kisskb/src/include/linux/kernel.h:15, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/ubifs/ubifs.h:16, from /kisskb/src/fs/ubifs/orphan.c:10: /kisskb/src/fs/ubifs/debug.h:158:11: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'ino_t' {aka 'unsigned int'} [-Wformat=] pr_debug("UBIFS DBG " type " (pid %d): " fmt "\n", current->pid, \ ^~~~~~~~~~~~ /kisskb/src/include/linux/printk.h:288:21: note: in definition of macro 'pr_fmt' #define pr_fmt(fmt) fmt ^~~ /kisskb/src/include/linux/dynamic_debug.h:143:2: note: in expansion of macro '__dynamic_func_call' __dynamic_func_call(__UNIQUE_ID(ddebug), fmt, func, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/dynamic_debug.h:153:2: note: in expansion of macro '_dynamic_func_call' _dynamic_func_call(fmt, __dynamic_pr_debug, \ ^~~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/printk.h:336:2: note: in expansion of macro 'dynamic_pr_debug' dynamic_pr_debug(fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~ /kisskb/src/fs/ubifs/debug.h:158:2: note: in expansion of macro 'pr_debug' pr_debug("UBIFS DBG " type " (pid %d): " fmt "\n", current->pid, \ ^~~~~~~~ /kisskb/src/fs/ubifs/debug.h:170:29: note: in expansion of macro 'ubifs_dbg_msg' #define dbg_gen(fmt, ...) ubifs_dbg_msg("gen", fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~ /kisskb/src/fs/ubifs/orphan.c:140:3: note: in expansion of macro 'dbg_gen' dbg_gen("delete later ino %lu", orph->inum); ^~~~~~~ /kisskb/src/fs/ubifs/orphan.c:140:31: note: format string is defined here dbg_gen("delete later ino %lu", orph->inum); ~~^ %u /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
