Konstantin Belousov 6e1eabadcb ffs_syncvnode(): avoid a LoR for SU
There is another case where SU code does ffs_syncvnode(dvp) for the
parent directory dvp while the child vnode vp is locked.  Avoid the
issue by relocking and returning ERELOOKUP to indicate the need of
resync.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.
