Alan Somers cf2ed0edae fusefs: fix an uninitialized memory access in fuse_vnop_deallocate
If the FUSE_GETATTR issued to query a file's size during
fuse_vnop_deallocate failed for any reason, then fuse_vnop_deallocate
would attempt to destroy an uninitialized fuse_dispatcher struct, with a
crash the likely result.  This bug only affects FUSE file systems that
implement FUSE_FALLOCATE, and is unlikely to be seen on those that don't
disable attribute caching.

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.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
