+
+	* inode.c (diskfs_cached_lookup): Use ino_t for argument.
+
+	* dir.c (diskfs_direnter_hard): Use size_t for OLDSIZE.

+
+2002-03-11  Roland McGrath  <roland@frob.com>
+

+
+2000-07-26  Mark Kettenis  <kettenis@gnu.org>

+	can happen through harmless races against truncate.

+	unallocated disk.  These can happen through harmless races against
+	truncate, and so we should not pester the console with them.

+
+1998-12-27  Roland McGrath  <roland@baalperazim.frob.com>

+
+	* sizes.c (diskfs_truncate): Don't acquire writer lock on

+
+	* main.c (main): Test getpid()>0 to decide we are a normal

+
+	* dir.c (diskfs_get_directs): When copying entries into DATAP,

+
+	* dir.c (dirscanblock): In main loop, initialize PREVOFF

+
+Mon Jun  6 19:23:26 1994  Michael I Bushnell  (mib@churchy.gnu.ai.mit.edu)
+
+	* sizes.c (diskfs_grow): After realloccg, zero new data (which I'm
+	not sure is really necessary, but until I figure it out, this is
+	safest).  Also poke old data (the latter only if the block has
+	moved)--otherwise the kernel won't know to page it out to the new
+	location.
+	(poke_pages): When poking, be careful not to actually change the data.
+	LEN should be end - start, not start - end.

+
+	* inode.c (iget): When we find the node in the table, acquire the

+	clear it after starting the write.
+
+	* main.c (main): Likewise.

+	* sizes.c (diskfs_truncate): Don't turn off caching; the new

+
+	* sizes.c (diskfs_truncate): After calling sin_unmap, turn
+	off caching on the sininfo pager so that it gets freed promptly
+	(there's generally no value in keeping it around because there
+	is no live fileinfo pager).
+	* pager.c (diskfs_get_filemap): Make sure we turn caching back on
+	here, however, if we start using the file pager.
+
+	* pager.c (sin_map): When np->dn->sininfo is set, we have
+	to insert a valid send right after fetching the receive name.

+
+	* sizes.c (diskfs_truncate): In blkfree loop of blocks past

+	need to truncate blocks (one) mapped by single indirect blocks.
+	(diskfs_truncate): New variable `first2free'.  Use in place
+	of older losing calculations involving lastblock.
+	(sindir_drop): Rename parameters to be FIRST and LAST.  Change
+	interpretation of FIRST by one to correspond with changed call
+	in diskfs_truncate.
+
+	* pager.c (sin_remap): When computing NEWSIZE, round up to
+	a page boundary, thus mimicing the SINDIR computation in
+	pager_report_extent properly.
+
+	* pager.c (pager_unlock_page) [case SINDIR; vblkno == 0]: Read

+	(blkpref) [!(lbn < NDADDR)]: Unlock alloclock before returning

+	...->di_ib.
+
+	* sizes.c (diskfs_grow): When writing into the SINDIR area, call
+	sin_map instead of sin_remap if the sindir isn't already mapped.

+	calling sin_remap, to meet the requirements of those separate
+	routines.
+
+	* sizes.c (diskfs_grow): If END isn't bigger than NP->allocsize,
+	then don't try and do anything.  In computation of LBN and the
+	first use of NB, round up to block boundary correctly.  Don't
+	attempt to realloc an old block if the size is 0 (in which case
+	NB is -1 and unsigned comparison rules might foul things up).
