[Xen-devel] [PATCH] libblktap: Remove trailing null byte in xs_printf

[Kevin Wolf <kwolf@xxxxxxx>]

xs_printf writes the terminating null byte of the passed string to
Xenstore. When reading, the null byte is returned in the following form
which confuses tools:

sector-size = "512\000"

This patch removes the null byte from the data to write.
