From f1b59d2620ae2bd977e67e292f9bebc43049872c Mon Sep 17 00:00:00 2001 From: behlendo Date: Wed, 27 Feb 2008 19:09:51 +0000 Subject: [PATCH] Lots of build fixes. This is turning out to be a very good idea since it forcefully codifing the ABI. Since the shim layer is no longer linked at build time in to the test suite we can;'t cut any corners and get away with it. Everything is working now with the exception of sorting setting Module.symvers properly. This may take a little Makefile reorg. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@5 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c --- include/linux-callb.h | 7 ++-- include/linux-condvar.h | 7 ++-- include/linux-cred.h | 7 ++-- include/linux-generic.h | 12 ++++--- include/linux-kmem.h | 23 ++++++------ include/linux-kstat.h | 7 ++-- include/linux-mutex.h | 10 +++--- include/linux-random.h | 7 ++-- include/linux-rwlock.h | 15 ++++---- include/linux-taskq.h | 7 ++-- include/linux-thread.h | 10 +++--- include/linux-time.h | 9 +++-- include/linux-timer.h | 7 ++-- include/linux-types.h | 6 ++-- include/splat-ctl.h | 73 ++++++++++++++++++++++++++++++++------- src/spl/Makefile.in | 3 +- src/spl/linux-generic.c | 8 +++++ src/spl/linux-kmem.c | 14 ++++---- src/spl/linux-rwlock.c | 4 +-- src/spl/linux-taskq.c | 6 ++-- src/spl/linux-thread.c | 11 +++--- src/splat/splat-condvar.c | 3 +- src/splat/splat-ctl.c | 21 ++++------- src/splat/splat-kmem.c | 7 ++-- src/splat/splat-mutex.c | 3 +- src/splat/splat-random.c | 3 +- src/splat/splat-rwlock.c | 3 +- src/splat/splat-taskq.c | 3 +- src/splat/splat-thread.c | 3 +- src/splat/splat-time.c | 3 +- 30 files changed, 182 insertions(+), 120 deletions(-) create mode 100644 src/spl/linux-generic.c diff --git a/include/linux-callb.h b/include/linux-callb.h index 6ffcfb76ed..0a34ad2cfa 100644 --- a/include/linux-callb.h +++ b/include/linux-callb.h @@ -1,10 +1,11 @@ -#ifndef _LINUX_CALLB_H -#define _LINUX_CALLB_H +#ifndef _SOLARIS_CALLB_H +#define _SOLARIS_CALLB_H #ifdef __cplusplus extern "C" { #endif +#include #include #define DEBUG_CALLB @@ -41,5 +42,5 @@ typedef struct callb_cpr { } #endif -#endif /* _LINUX_CALLB_H */ +#endif /* _SOLARIS_CALLB_H */ diff --git a/include/linux-condvar.h b/include/linux-condvar.h index e4a1779a53..8f5cb922a5 100644 --- a/include/linux-condvar.h +++ b/include/linux-condvar.h @@ -1,10 +1,11 @@ -#ifndef _LINUX_CONDVAR_H -#define _LINUX_CONDVAR_H +#ifndef _SOLARIS_CONDVAR_H +#define _SOLARIS_CONDVAR_H #ifdef __cplusplus extern "C" { #endif +#include #include /* The kcondvar_t struct is protected by mutex taken externally before @@ -198,4 +199,4 @@ cv_broadcast(kcondvar_t *cvp) if (atomic_read(&cvp->cv_waiters) > 0) wake_up_all(&cvp->cv_event);
