Bash allows functions to be declared with or without the leading keyword 'function'; but including the keyword does not comply with POSIX syntax, and is confusing to ksh users where the use of the keyword changes the scoping rules for functions. Stick to the POSIX form through iotests. Done mechanically with: sed -i 's/^function //' $(git ls-files tests/qemu-iotests) Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20181116215002.2124581-1-eblake@redhat.com> Reviewed-by: Daniel P.
