But # instead of the '_and_lock()' naming it uses '_or_lock()'. # # And instead of returning true in case it took the lock, it returns true # if it didn't* take the lock. # # Now, arguably the reflock code is quite logical: it really is a "either # decrement _or_ lock" kind of situation - and the return value is about # whether the operation succeeded without any special care needed. # # So despite the similarities, the differences do make some sense, and # maybe it's not worth trying to unify the different conditional locking # primitives in this area. # # But while looking at this all, it did become obvious that the # 'lockref_get_or_lock()' function hasn't actually had any users for # almost a decade. # # The only user it ever had was the shortlived 'd_rcu_to_refcount()' # function, and it got removed and replaced with 'lockref_get_not_dead()' # back in 2013 in commits 0d98439ea3c6 ("vfs: use lockred 'dead' flag to # mark unrecoverably dead dentries") and e5c832d55588 ("vfs: fix dentry # RCU to refcounting possibly sleeping dput()") # # In fact, that single use was removed less than a week after the whole # function was introduced in commit b3abd80250c1 ("lockref: add # 'lockref_get_or_lock() helper") so this function has been around for a # decade, but only had a user for six days. # # Let's just put this mis-designed and unused function out of its misery. # # We can think about the naming and semantic oddities of the remaining # 'lockref_put_or_lock()' later, but at least that function has users. # # And while the naming is different and the return value doesn't match, # that function matches the whole '{atomic,refcount}_dec_and_test()' # pattern much better (ie the magic happens when the count goes down to # zero, not when it is incremented from zero). # # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 b8d5109f50969ead9d49c3e8bd78ec1f82e548e3 # < make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 40 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: modpost: EXPORT symbol "empty_zero_page" [vmlinux] version generation failed, symbol will not be versioned.
