Modified files:
sys/kern vfs_bio.c
sys/sys buf.h
sys/ufs/ffs ffs_softdep.c
Log:
- Define a new flag for getblk(): GB_NOCREAT. This flag causes getblk() to
bail out if the buffer is not already present.
- The buffer returned by incore() is not locked and should not be sent to
brelse(). Use getblk() with the new GB_NOCREAT flag to preserve the
desired semantics.
