It just reports the total number of # dentries in the LRU lists. # # As excessive number of negative dentries can have an impact on system # performance, it will be wise to track the number of positive and # negative dentries separately. # # This patch adds tracking for the total number of negative dentries in # the system LRU lists and reports it in the 5th field in the # /proc/sys/fs/dentry-state file. The number, however, does not include # negative dentries that are in flight but not in the LRU yet as well as # those in the shrinker lists which are on the way out anyway. # # The number of positive dentries in the LRU lists can be roughly found by # subtracting the number of negative dentries from the unused count. # # Matthew Wilcox had confirmed that since the introduction of the # dentry_stat structure in 2.1.60, the dummy array was there, probably for # future extension. They were not replacements of pre-existing fields. # So no sane applications that read the value of /proc/sys/fs/dentry-state # will do dummy thing if the last 2 fields of the sysctl parameter are not # zero. IOW, it will be safe to use one of the dummy array entry for # negative dentry count. # # Signed-off-by: Waiman Long <longman@redhat.com> # 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 af0c9af1b3f66052c369d08be3f60fa9a9559e48 # < make -s -j 8 ARCH=arm O=/kisskb/build/linus_mmp2_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- mmp2_defconfig # make -s -j 8 ARCH=arm O=/kisskb/build/linus_mmp2_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/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:133:34: warning: 'levelspread[<Ufaa0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:100:6: note: 'levelspread[<Ufaa0>]' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2594:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' 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/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 [-Wuninitialized] /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_mmp2_defconfig_arm # Build took: 0:01:06.017040
