Subject: [PATCH] fs: fat: enable VFAT long file names by default
Date: Wed, 13 Sep 2023 12:35:52 +0200	[thread overview]
Message-ID: <> (raw)

Apparently, this option defaulted to 'n' since the very beginning, so
users newly enabling FAT may unwittingly run into a cryptic:

  barebox@board:/ cp something /mnt/mmc0.0/freertos-main.elf
  could not open /mnt/mmc0.0/freertos-main.elf: Invalid argument

As FAT file systems nowadays are VFAT by default and allow up to 255
characters in file names, there's no reason to restrict barebox to
classic 8.3 file names by default.
