Subject: [PATCH] libblktap: Remove trailing null byte in xs_printf
Date: Thu, 02 Oct 2008 13:51:19 +0200 [thread overview]
Message-ID: <48E4B5B7.1080209@suse.de> (raw)
[-- Attachment #1: Type: text/plain, Size: 287 bytes --]
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.
