[PATCH 2/2] audit: fix sparse shadowed variable warnings
Use msglen as the identifier. kernel/audit.c:724:10: warning: symbol 'len' shadows an earlier one kernel/audit.c:575:8: originally declared here Don't use ino_f to check the inode field at the end of the functions. kernel/auditfilter.c:429:22: warning: symbol 'f' shadows an earlier one kernel/auditfilter.c:420:21: originally declared here kernel/auditfilter.c:542:22: warning: symbol 'f' shadows an earlier one kernel/auditfilter.c:529:21: originally declared here i always used as a counter for a for loop and initialized to zero before use. Eliminate the inner i variables. kernel/auditsc.c:1295:8: warning: symbol 'i' shadows an earlier one kernel/auditsc.c:1152:6: originally declared here kernel/auditsc.c:1320:7: warning: symbol 'i' shadows an earlier one kernel/auditsc.c:1152:6: originally declared here Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
