Description Alan Somers freebsd_committer freebsd_triage 2019-06-05 16:24:30 UTC 
r236321 added a new mechanism for avoiding lock order reversals when a program reads from one file into a buffer backed by another file.  This mechanism mostly takes place in the VFS, but file systems need to opt in.  See the comments for vn_io_fault_doio.  fusefs should do it.
