[lvm-devel] LVM2/lib/format_text import_vsn1.c

[zkabelac at sourceware.org]

CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac at sourceware.org	2012-02-27 11:40:58

Modified files:
	lib/format_text: import_vsn1.c 

Log message:
	Just code move of hash initialization in front of function
	
	Make sure both hash tables are initialized before _read_sections() call.
	Presents no functional change (since PV scan phase was not adding LV hashes),
	but makes the code easier to handle mem failing case, and static analyzer is
	hapier as well.
