Here is a series of patches to make the procfs internals private to the procfs filesystem. This is built on top of the patches to eliminate create_proc_read_entry() after the kill-read_proc_t tag. These patches include fixes for the places that are attempting to abuse proc_dir_entry->count and doing it incorrectly because PID namespaces now exist. All accesses to the PDE struct have been replaced with out-of-line accessor functions. This is a bit less efficient than it used to be, but this could be mitigated by using inode->i_private. The internal procfs structs have moved to fs/procfs/internal.h. Some of the remaining stuff in linux/proc_fs.h has been split out to linux/kcore.h and linux/proc_ns.h as they's separate specialised intefaces. These patches can be seen here also: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=vfs-experimental David --- David Howells (28): Include missing linux/slab.h inclusions Include missing linux/magic.h inclusions proc: Split kcore bits from linux/procfs.h into linux/kcore.h proc: Supply PDE attribute setting accessor functions proc: Uninline pid_delete_dentry() proc: Move proc_fd() to fs/proc/fd.h proc: Split the namespace stuff out into linux/proc_ns.h proc: Move PDE_NET() to fs/proc/proc_net.c proc: Move some bits from linux/proc_fs.h to linux/{of.h,signal.h,tty.h} proc: Add proc_mkdir_data() rtl8187se: Use a dir under /proc/net/r8180/ rtl8192u: Don't need to save device proc dir PDE airo: Use remove_proc_subtree() proc: Supply an accessor for getting the data from a PDE's parent reiserfs: Don't access the proc_dir_entry in r_open(), r_start() r_show() zoran: Don't print proc_dir_entry data in debug drm: Constify drm_proc_list[] drm: proc: Use minor->index to label things, not PDE->name drm: proc: Use remove_proc_subtree() hostap: proc: Use remove_proc_subtree() dgrp: Clean up the use of procfs ppc: Clean up rtas_flash driver somewhat ppc: Clean up scanlog proc: Supply an accessor to get the name in a proc_dir_entry struct proc: Supply an accessor to get the process ID associated with some proc files proc: Supply a function to remove a proc entry by PDE proc: Make the PROC_I() and PDE() macros internal to procfs proc: Move non-public stuff from linux/proc_fs.h to fs/proc/internal.h arch/mips/mm/init.c | 1 arch/powerpc/kernel/proc_powerpc.c | 2 arch/powerpc/kernel/rtas_flash.c | 446 +++++++++++++---------------- arch/powerpc/platforms/pseries/reconfig.c | 2 arch/powerpc/platforms/pseries/scanlog.c | 29 +- arch/s390/kernel/os_info.c | 1 arch/score/mm/init.c | 2 arch/sparc/kernel/sun4d_irq.c | 1 arch/x86/mm/init_64.c | 1 arch/x86/platform/efi/efi.c | 1 arch/x86/platform/efi/efi_64.c | 1 drivers/acpi/sbs.c | 21 - drivers/char/ipmi/ipmi_msghandler.c | 2 drivers/firmware/efivars.c | 1 drivers/gpu/drm/drm_proc.c | 41 +-- drivers/gpu/drm/drm_stub.c | 2 drivers/media/pci/ttpci/av7110_ir.c | 2 drivers/media/pci/zoran/zoran_procfs.c | 2 drivers/message/i2o/i2o_proc.c | 8 - drivers/misc/sgi-gru/gruprocfs.c | 2 drivers/mtd/mtdcore.c | 1 drivers/net/irda/vlsi_ir.c | 2 drivers/net/wireless/airo.c | 83 ++--- drivers/net/wireless/hostap/hostap_proc.c | 20 - drivers/of/base.c | 11 - drivers/pci/proc.c | 14 - drivers/pps/clients/pps_parport.c | 1 drivers/scsi/megaraid.c | 6 drivers/staging/dgrp/dgrp_dpa_ops.c | 1 drivers/staging/dgrp/dgrp_mon_ops.c | 1 drivers/staging/dgrp/dgrp_net_ops.c | 2 drivers/staging/dgrp/dgrp_specproc.c | 83 ++--- drivers/staging/rtl8187se/r8180.h | 1 drivers/staging/rtl8187se/r8180_core.c | 28 +- drivers/staging/rtl8192u/r8192U.h | 1 drivers/staging/rtl8192u/r8192U_core.c | 21 - fs/namespace.c | 6 fs/proc/base.c | 14 + fs/proc/fd.h | 5 fs/proc/generic.c | 71 +++-- fs/proc/inode.c | 9 - fs/proc/internal.h | 346 +++++++++++++++------- fs/proc/kcore.c | 2 fs/proc/namespaces.c | 17 + fs/proc/proc_devtree.c | 2 fs/proc/proc_net.c | 4 fs/proc/self.c | 1 fs/proc/vmcore.c | 5 fs/reiserfs/procfs.c | 32 +- include/drm/drmP.h | 5 include/linux/kcore.h | 38 ++ include/linux/of.h | 10 + include/linux/proc_fs.h | 299 +++---------------- include/linux/proc_ns.h | 74 +++++ include/linux/signal.h | 5 include/linux/tty.h | 7 init/version.c | 2 ipc/msgutil.c | 2 ipc/namespace.c | 2 kernel/cgroup.c | 3 kernel/configs.c | 2 kernel/cpuset.c | 3 kernel/irq/proc.c | 6 kernel/nsproxy.c | 6 kernel/pid.c | 1 kernel/pid_namespace.c | 2 kernel/profile.c | 2 kernel/user.c | 2 kernel/user_namespace.c | 2 kernel/utsname.c | 2 net/8021q/vlanproc.c | 9 - net/core/net_namespace.c | 7 net/core/pktgen.c | 6 net/ipv4/netfilter/ipt_CLUSTERIP.c | 4 net/ipv6/proc.c | 3 net/netfilter/xt_hashlimit.c | 6 net/netfilter/xt_recent.c | 3 sound/core/info.c | 21 - 78 files changed, 898 insertions(+), 994 deletions(-) create mode 100644 include/linux/kcore.h create mode 100644 include/linux/proc_ns.h -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
