Revision 1.220, Fri Apr 25 10:58:04 2003 UTC (14 years, 6 months ago) by lord
Branch: MAIN
Changes since 1.219: +131 -95
lines
Add some new debugging commands to XFS. Allow us to list the
delayed write metadata buffers, and vfs and super block basics.
Also update the printing of some list pointers so we print the
address of the data structure rather than the address of the
list entry within it.
ad pbdelay, rework pb command to dump pagebuf pointers rather than
the list pointers within them when showing list information.
