From bdf4328b04544ac3759d689d0a68e514b6df1025 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Tue, 22 Mar 2011 09:55:09 -0700 Subject: Linux 2.6.28 compat, insert_inode_locked() Added insert_inode_locked() helper function, prior to this most callers used insert_inode_hash(). The older method doesn't check for collisions in the inode_hashtable but it still acceptible for use. Fallback to using insert_inode_hash() when insert_inode_locked() is unavailable. --- config/kernel-insert-inode-locked.m4 | 12 ++++++++++++ config/kernel.m4 | 1 + 2 files changed, 13 insertions(+) create mode 100644 config/kernel-insert-inode-locked.m4 (limited to 'config') diff --git a/config/kernel-insert-inode-locked.m4 b/config/kernel-insert-inode-locked.m4 new file mode 100644 index 000000000..1faff7e64 --- /dev/null +++ b/config/kernel-insert-inode-locked.m4 @@ -0,0 +1,12 @@ +dnl # +dnl # 2.6.28 API change +dnl # Added insert_inode_locked() helper function. +dnl # +AC_DEFUN([ZFS_AC_KERNEL_INSERT_INODE_LOCKED], [ + ZFS_CHECK_SYMBOL_EXPORT( + [insert_inode_locked], + [fs/inode.c], + [AC_DEFINE(HAVE_INSERT_INODE_LOCKED, 1, + [insert_inode_locked() is available])], + []) +]) diff --git a/config/kernel.m4 b/config/kernel.m4 index 2b4df7023..510f6dbc7 100644 --- a/config/kernel.m4 +++ b/config/kernel.m4 @@ -34,6 +34,7 @@ AC_DEFUN([ZFS_AC_CONFIG_KERNEL], [ ZFS_AC_KERNEL_XATTR_HANDLER_SET ZFS_AC_KERNEL_FSYNC_2ARGS ZFS_AC_KERNEL_EVICT_INODE + ZFS_AC_KERNEL_INSERT_INODE_LOCKED if test "$LINUX_OBJ" != "$LINUX"; then KERNELMAKE_PARAMS="$KERNELMAKE_PARAMS O=$LINUX_OBJ" -- cgit v1.2.3
