Subject: [PATCH 19/23] libctf: do not use mmap on Solaris 11
|
|
|
|
Writable mmaps and read are inconsistent with each other on Solaris 11.4,
|
|
which breaks archive writing. Simply assert that Solaris 2.11 doesn't have
|
|
mmap, falling back to read(): the archive format is being bumped shortly, to
|
|
one with completely different writeout code, so this workaround need not
|
|
stay for long.
