Subject: Remove compat includes from sys/types.h
X-Git-Tag: spl-0.7.12~214
X-Git-Url: https://git.proxmox.com/?p=mirror_spl.git;a=commitdiff_plain;h=52479ecf58fa89190e384edcf838fecccc786af5

Remove compat includes from sys/types.h

Don't include the compatibility code in linux/*_compat.h in the public
header sys/types.h. This causes problems when an external code base
includes the ZFS headers and has its own conflicting compatibility code.
Lustre, in particular, defined SHRINK_STOP for compatibility with
pre-3.12 kernels in a way that conflicted with the SPL's definition.
Because Lustre ZFS OSD includes ZFS headers it fails to build due to a
'"SHRINK_STOP" redefined' compiler warning.  To avoid such conflicts
only include the compat headers from .c files or private headers.

Also, for consistency, include sys/*.h before linux/*.h then sort by
header name.
