[Xen-devel] [PATCH] Compile issue with tools/libfsimage/iso9660

Compile issue with tools/libfsimage/iso9660

char vs unsigned char signedness causes a warning when compiling
iso9660 (xen-unstable). This patch changes the unsigned char * for
char *.

A similar patch has been in xen-unstable for a fortnight. Where do you get
your bits from?

Maybe something went wrong with the merge and I missed it ?

The existing changeset that fixes this issue is 14038:335a8280ab1d9a87.
Perhaps you have pulled the latest changesets into your local repository but
not updated you locally-checked-out copy? How do ''hg heads''
and ''hg parents''
match up for you?

I have :

compudj@dijkstra:~/xen/xen-unstable-lttng.hg$ hg heads
changeset:   14209:d62b52c15b53
tag:         tip

I guess I should merge 14206:3ac19fda0bc2 into tip ?

The issue seems solved :

compudj@dijkstra:~/xen/xen-unstable-lttng.hg$ hg merge 14206
merging tools/libfsimage/iso9660/fsys_iso9660.c
merging xen/common/sysctl.c
merging xen/include/asm-x86/config.h
345 files updated, 3 files merged, 1 files removed, 0 files unresolved


Thanks,

Mathieu
