Subject: [PATCH v2 1/1] fs/read_write: Do not export __kernel_write() to the entire world
Date: Thu, 4 Jun 2026 11:52:02 +0200 [thread overview]
Message-ID: <20260604095233.284067-1-andriy.shevchenko@linux.intel.com> (raw)
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.
