New Revision: 233653
URL: http://svn.freebsd.org/changeset/base/233653
Log:
MFC r232835:
Do not fall back to slow synchronous i/o when low on memory or buffers.
The bawrite() schedules the write to happen immediately, and its use
frees the current thread to do more cleanups.
MFC r232837:
Remove superfluous brackets.
