+
+Mon May 8 08:43:43 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
+
+ * dir.c (diskfs_lookup): When looping back to try_again: because

+
+ * sizes.c (diskfs_truncate): Don't acquire writer lock on
+ NP->dn->allocptrlock until after forcing delayed copies through;

+
+ * inode.c (read_disknode): If we are the bootstrap filesystem,

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

+
+ * 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.
+
+Fri Jun 3 12:37:27 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu)
+
+ * inode.c (iget): When we find the node in the table, acquire the

+
+ * 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

+ * 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

+ (diskfs_truncate): If olastblock == NDADDR, then we also
+ need to truncate blocks (one) mapped by single indirect blocks.
+ (diskfs_truncate): New variable `first2free'. Use in place

+ interpretation of FIRST by one to correspond with changed call

+
+ * pager.c (sin_remap): When computing NEWSIZE, round up to
+ a page boundary, thus mimicing the SINDIR computation in
+ pager_report_extent properly.

+ ...->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.

+ 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

+ NB is -1 and unsigned comparison rules might foul things up).

+
+ * alloc.c (realloccg): When fragextend succeeds, bother to set
+ *PBN.
+
+ * sizes.c (diskfs_grow): In fragment growth case, NSIZE should

+ SIZE.
+
