37TODO: mmap on $hash->{key} keeps PVLV
38 - new aio_slurp request.
39 - removed filesystem magic number table from aio_statvfs docs as
40 statvfs doesn't actually return this info at all (statfs does).
41 - add a bunch of (mostly linux-specific) constants for use in ioctls
42 (see aio_ioctl docs).
43 - treescan now has a proper manpage and useful --help output.
44 - new option --sync in treescan, to sync everything in a subtree.
45 - changed default for aio_msync flags to MSYNC_SYNC.
46 - document offset/length behaviour of mprotect/madvise.
47 - support linux's renameat2 (via aio_rename2).
48 - add aio_rename2, an aio_rename with flags.
49 - add F_DUPPFD_CLOEXEC, F_OFD_[SG]ETLKW? constants.
50 - add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
51 - add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
52 - point out that aio_copy overwrites existing files.
53 - (libeio) use posix_close if available.
54 - (libeio) internal close() calls no longer disturb errno.
55 - add IO:AIO::FALLOC_FL_UNSHARE.
56 - update schmorp.h for removal of USE_SOCKETS_AS_HANDLES.
57
584.34 Sun May 1 19:18:24 CEST 2016
59 - def0.h was not properly generated during previous release, causing
60 compile errors on various platforms.
61 - major/minor were accidentally switched (reported by Alexander Lishenyuk).
62 - removed duplicate definition of MAP_HUGETLB, that was found due to
63 a bug in Perl::Tidy (testcase by alaska332@gmail.com).
64 - added (untested!) aio_fcntl, aio_ioctl requests.
65 - (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
66 as manpages-dev originally claimed.
67
684.33 Mon Jan 18 12:50:10 CET 2016
69 - add IO::AIO::pipe2 function.
70 - added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
71 constants.
72 - added support for O_TMPFILE and O_PATH constants.
73 - added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
74 consdtants, whether they can be sensibly used or not.
75 - use NO_INIT where applicable.
76 - update libecb.
77 - added stability canary support.

87
884.3 Fri Apr 11 06:22:38 CEST 2014
89 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
90 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
91 in 5.18. What's so attractive about giving a shit about backwards
92 compatibility - I will never understand.
93
944.2 Sat Jan 25 01:13:14 CET 2014
95 - aio_group could corrupt memory because it didn't restore

114 - add list of linux fsid values to aio_statvfs docs.
115 - work around a bug in btrfs' FIEMAP ioctl implementation.

117 as per unix spec.
118
1194.16 Tue Aug 14 05:39:03 CEST 2012
120 - aio_statvfs was wromgly marked for wd emulation, causing
121 it to malfunction for paths.
122 - fix a crash in aio_fiemap, when used on ranges without any

124 - work around linux kernel bug (at least in 3.2): kernel might
125 trash fiemap input arguments.
126 - work around linux kernel bug (at least in 3.2): kernel does not
127 set FIEMAP_EXTENT_LAST on last segment.
128 - work around linux kernel bug (at least in 3.2): kernel silently
129 truncates segment count if a file.
12 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap 130 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
13 to quick overview. 131 to quick overview.
14 - splice can corrupt data. 132 - splice can corrupt data.

135 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
136 - provide pread/pwrite for win32, making it link again on native win32.
