[Qemu-devel] [PATCH][STABLE] user: Restore debug usage message for '-d ?' in user mode emulation |
Date: |
Sat, 30 Jul 2011 13:18:35 +0100 |
The code which prints the debug usage message on '-d ?' for *-user
has to come before the check for "not enough arguments", so that
"qemu-foo -d ?" prints the list of possible debug log items rather than
the generic usage message. (This was inadvertently broken in commit
c235d73.)

This is just a retransmit of this patch (applied in master as 4b5dfd824)
with the appropriate magic markers to say "please apply to 0.15 as well",
since it's a regression from 0.14.
