sys/compat/linprocfs linprocfs.c
Log:
Lock the vnode around the call to VOP_GETATTR. Move the locked code
and vn_fullpath (that call malloc(..., M_WAITOK)) from under the
vm object lock, since sleep is not allowed while holding the mutex.
Being there, wrap VOP_GETATTR call with conditional Giant aquire.
Currently this is (almost) noop because pseudofs is Giant-locked.
