Fixed bug where lvresize option -t was not properly passed to fsadm.
Using argv[] list in exec_cmd() to allow more params for external commands. Fsadm does not allow checking mounted filesystem. Fsadm no longer accepts 'any other key' as 'no' answer to y/n. Fsadm improved handling of command line options.

Version 2.02.45 -
|
||||
===================================
|
||||
Fixed bug where lvresize option -t was not properly passed to fsadm.
|
||||
Using argv[] list in exec_cmd() to allow more params for external commands.
|
||||
Fsadm does not allow checking mounted filesystem.
|
||||
Fsadm no longer accepts 'any other key' as 'no' answer to y/n.
|
||||
Fsadm improved handling of command line options.
|
||||
Add lib/lvm.h and lib/lvm_base.c for the new library interface.
|
||||
Move tools/version.h to lib/misc/lvm-version.h.
|
||||
Split LVM_VERSION into MAJOR, MINOR, PATCHLEVEL, RELEASE and RELEASE_DATE.
