From 1a571226cb82503839c6c284d3c7a172c93f19c4 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 4 Jun 2026 11:52:02 +0200 Subject: [PATCH] fs/read_write: Do not export __kernel_write() to the entire world Since we have EXPORT_SYMBOL_FOR_MODULES(), we may narrow the __kernel_write() export to the only which really needs it. With that being done, update the respective comment.
