 123
 124 perf_event_open.2
 125     Vince Weaver
 126         Clarify description of overflow events
 127             Update the perf_event_open manpage to be more consistent when
 128             discussing overflow events.  It merges the discussion of
 129             poll-type notifications with those generated by SIGIO
 130             signal handlers.
 131             This addresses the remaining FIXMEs is the document.
 132     Vince Weaver
 133         Remove inaccurate paragraph describing attr.config
 134             Remove an inaccurate paragraph about values in the attr.config
 135             field.  This information was never true in any released kernel;
 136             it somehow snuck into the manpage because it is still described
 137             this way in tools/perf/design.txt in the kernel source tree.
 138     Michael Kerrisk
 139         Correct the kernel version number for PERF_COUNT_HW_CACHE_NODE
 140     Michael Kerrisk
 141         Add some kernel version numbers to various fields and constants
 142
 143 ptrace.2
 144 sigaction.2
 145 seccomp.2
 146     Kees Cook
 147         Ptrace and siginfo details
 148             While writing some additional seccomp tests, I realized
 149             PTRACE_EVENT_SECCOMP wasn't documented yet. Fixed this, and added
 150             additional notes related to ptrace events SIGTRAP details.
 151
 152 readv.2
 153     Michael Kerrisk
 154         Update details on glibc readv()/writev() wrapper behavior
 155             And add a historical detail about Linux 2.0.
 156
 157 select.2
 158     Michael Kerrisk
 159         Mention RLIMIT_NOFILE as a possible cause of EINVAL error
 160
 161 syscall.2
 162     Kees Cook
 163         Add arm64 and mips
 164             Add mips an d arm64 to tables, along with some further
 165             details on these architectures,
 166
 167 syscalls.2
 168     Michael Kerrisk
 169         Add s390_pci_mmio_read(2) and s390_pci_mmio_write(2)
 170     Michael Kerrisk
 171         Note kernel() version that introduced get_kernel_syms()
 172         Note kernel version that introduced ppc_rtas()
 173         Note kernel version that introduced create_module()
 174         Note kernel version that added setup()
 175     Michael Kerrisk
 176         Remove some details for sync_file_range2()
 177             Make the table a bit simpler. The details can anyway be
 178             found in the system call man page.
 179
 180 utimensat.2
 181     Michael Kerrisk  [Elliot Hughes]
 182         If both tv_sec fields are UTIME_OMIT, the file need not exist
 183             As noted by Elliot, if both tv_sec fields are UTIME_OMIT,
 184             utimensat() will return success even if the file does not exist.
 185
 186 errno.3
 187     Michael Kerrisk
 188         The RLIMIT_NOFILE resource limit is a common cause of EMFILE
 189
 190 exec.3
 191     Michael Kerrisk
 192         SEE ALSO: add execveat(2)
 193
 194 fclose.3
 195     Carlos O'Donell
 196         Consistency fix: use "stream" as name for "FILE *" argument
 197             Harmonize all the manual pages to use "stream" for FILE*
 198             instead of randomly using "fp" or "stream." Choosing something
 199             and being consistent helps users scan the man pages quickly
 200             and understand what they are looking at.
 201
 202 fexecve.3
 203     Michael Kerrisk
 204         Rewrite the script+close-on-exec problem as a BUG
 205             Also, add one or two details about this scenario.
 206     Michael Kerrisk
 207         The natural idiom when using fexecve() is to use the close-on-exec flag
 208
 209 fmemopen.3
 210     Michael Kerrisk
 211         Consistency fix: use "stream" as name for "FILE *" argument
 212
 213 fopencookie.3
 214     Michael Kerrisk
 215         Consistency fix: use "stream" as name for "FILE *" argument
 216

 218     Carlos O'Donell
 219         Consistency fix: use "stream" as name for "FILE *" argument
 220
 221 getline.3
 222     Michael Kerrisk
 223         Consistency fix: use "stream" as name for "FILE *" argument
 224
 225 getmntent.3
 226     Carlos O'Donell
 227         Consistency fix: use "stream" as name for "FILE *" argument

 234     Carlos O'Donell
 235         Consistency fix: use "stream" as name for "FILE *" argument
 236
 237 getspnam.3
 238     Carlos O'Donell
 239         Consistency fix: use "stream" as name for "FILE *" argument
 240
 241 malloc_info.3
 242     Carlos O'Donell
 243         Consistency fix: use "stream" as name for "FILE *" argument
 244
 245 posix_fallocate.3
 246     Michael Kerrisk
 247         Note that posix_fallocate() is implemented using fallocate(2)
 248
 249 putgrent.3
 250     Carlos O'Donell
 251         Consistency fix: use "stream" as name for "FILE *" argument
 252             Harmonize all the manual pages to use "stream" for FILE*
 253             instead of randomly using "fp" or "stream." Choosing something
 254             and being consistent helps users scan the man pages quickly
 255             and understand what they are looking at.
 256

 259         Correct variable name
 260
 261 proc.5
