'int compress' in savecore.c and the function 'compress' in libz.
Gnu ld 2.10 (with BFD 2.10) used on sparc64 warns this conflict
(symbol "compress" changed size).
Some years ago I made it O(n^2).
Someone helpfully made it O(n^4) again.
Today I'm making it O(n).
If that's not good enough, I don't know what else to do. B-)
Technical details:
* The graph traversal in propagate() is modified to be able to start from any
point in the tree. To handle certain exceptional cases, it is also modified
to work in two passes, marking the tree with a special tag and then changing
it to DFOUND.
* The reconnect case now modifies the child/sibling pointers and calls
propagate() to propagate the connection state starting with the reconnected
directory.
Pray that you never encounter a file system trashed enough for this to matter.
too damn small) by setting a minimum (1024) and maximum (maxino + 1). This
prevents certain operations getting REALLY slow when -b is used, and also
avoids overallocating memory if the superblock is hosed.
already. So, don't fail if there appears to be a corrupt label or
no 'fake' label; get the 'default' label (which is generated
from DIOCGDEFLABEL) instead.
this fixes a problem where elf_mod_sizes() would report size which would
be different (smaller) that the actual size of LKM code to be loaded in some
cases

-w write in-core label if changed
-r update on-disk as well as in-core label (with -w)
-f force update (-w), even if there's been no change
-r behaviour suggested by matt green. what used to be `-f' is now `-wrf'
gotten bitten by mbrlabel trashing my incore disklabel to a point where
the machine wasn't usable, so I reworked it:
* only update the incore (and on-disk) label if `-f' is given. by default,
the proposed disklabel will be printed but no changes will occur
* add -q, to make the default operation a bit more quiet.
* leave existing `used' in-core partition slots alone, and only add entries
to the incore label if:
- there's not an existing partition of the same size and offset
(even of a different type)
- there's a free partition slot (`unused', with size == 0)
* use DIOCWDINFO instead of DIOCSDINFO, to update the incore as well as
the on-disk label
* use showpartitions() from ../disklabel/printlabel.c
this should make mbrlabel a *lot* more useful.
