New Revision: 295098
URL: https://svnweb.freebsd.org/changeset/base/295098
Log:
Fix the logic in the ddb command 'show ktr /a'. Prior to r118269 it would
print until cncheckc returned a non -1, i.e. a character had been entered.
After this change it would print only if cncheckc returned a character.
As this was before each call to db_mach_vtrace the normal outcome was
nothing was printed.
With this change 'show ktr /a' will now keep printing until the user stops
the command with a key press, or there is no more entries to print.
