Without this patch, git-rev-list unnecessarily omits strerror(errno) from its diagnostic, upon write failure: $ ./git-rev-list --max-count=1 HEAD > /dev/full fatal: write failure on standard output With the patch, git reports the desired ENOSPC diagnostic: fatal: write failure on standard output: No space left on device * builtin-rev-list (show_commit): Diagnose a failed fflush call.
