Introducing buf_adjcnt() from Bitrig. It is needed to notify WAPBL that the buffer has size changes. -- Walter Neto diff --git a/sys/kern/vfs_bio.c b/sys/kern/vfs_bio.c index 9bf9b36..459b4fa 100644 --- a/sys/kern/vfs_bio.c +++ b/sys/kern/vfs_bio.c @@ -1206,6 +1206,14 @@ bcstats_print

WAPBL: Adding the FFS capability to alloc files contiguously

This diff adds B_CONTIG and B_METAONLY low-level allocation flags, and the code to FFS allocate contiguously files. This will be used to alloc WAPBL log file. -- Walter Neto diff --git a/sys/sys/buf.h b/sys/sys/buf.h index c47f3f9..fd38c28 100644 --- a/sys/sys/buf.h +++ b/sys/sys/buf.h

Hy.. I want to help OpenBSD developing a journaling system for UFS. Someone can give me a tip? Thanks.
