Description
I was using Haiku to compile a large amount of code, and then, when using another application, Haiku went into the KDL. This is with hrev54185 on a x86_gcc2 machine. I’ve heard about this issue being about something to do with the file_cache possibly?

This looks like it is in the VFS layer. This is indeed very interesting, I wonder if it's related to some of the rare file corruptions X512 has mentioned.

The problem is here: https://xref.landonf.org/source/xref/haiku/src/system/kernel/cache/file_cache.cpp#1327
The write operation always uses kZeroVecCount and not the appropriate number of pages. This loop needs to be refactored; and probably some of these variables renamed for clarity.

Fixed again more properly in hrev54281.
