Status as of 14 June 2005:

- Patch to handle reentrancy currently in -mm (2.6.12-rc6-mm1). Has been through
community review and Andi Kleen indicated he is ok with merging this upstream
post 2.6.12
Comment 2 Prasanna S Panchamukhi 2005-08-30 11:30:29 UTC 
To provide reentrancy feature, reentred kprobes are temporarily disarmed. This
feature is supported in all architectures i386, x86_64, ia64, sparc64, ppc64.
Patch set to support this feature was included in 2.6.13-rc1 release kernel on
28 June 2005.

Thanks
