From 2c33b0c7d8deca7e9a907365a59fcbcde531c70d Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Thu, 21 Dec 2017 12:49:47 +0100 Subject: [PATCH] fat write: Fixed a problem with the case of file names when writing files commit 21a24c3bf35b ("fs/fat: fix case for FAT shortnames") made it possible that get_name() returns file names with some upper cases. find_directory_entry() must be updated to take this account, and use case-insensitive functions to compare file names.
