Bug #2374: softupdates locking bug
Author: Venkatesh Srinivas
softupdates may still have some locking issues:
Panic where softdep_update_inodeblock() called bwrite() with a NULL buffer
getdirtybuf returned 'gotit', yet it either returned a NULL bp or the buffer was nulled after
it was saved in the inodedep structure. getdirtybuf can block and does release the softdep
lock while locking dirty buffers, but it is not clear if anyone can race in and result in the failure mode seen.
* (from 3.0.3 catchall bug (2336)):
Deadlock in -master with softdep. No more details available.
