Re: [libvirt] [PATCHv5 1/7] storage: Add APIs for internal handling of files via the storage driver

Some remote filesystems are not accessible via the local filesystem calls, but libvirt needs means to do operations on such files. This patch adds internal APIs into the storage driver that will allow operations on various networked and other filesystems. --- Notes: Version 5: - changed error reporting scheme and re-documented - fix indentation of makefile - simplified conditions according to review - fixed typos docs/hvsupport.pl | 4 +- po/POTFILES.in | 1 + src/Makefile.am | 1 + src/check-drivername.pl | 1 + src/driver.h | 30 +++++++- src/libvirt_private.c | 180 +++++++++++++++++++++++++++++++++++++++++++++++ src/libvirt_private.h | 61 ++++++++++++++++ src/libvirt_private.syms | 9 +++ 8 files changed, 285 insertions(+), 2 deletions(-) create mode 100644 src/libvirt_private.c create mode 100644 src/libvirt_private.h
