Check out-of-memory failure of the kstrdup option. Note that the argument "arg" may be NULL (in that case kstrup returns NULL), so out of memory condition happened if arg was non-NULL and kstrdup returned NULL. The patch also changes the call to replace_mount_options - if we didn't pass any filesystem-specific options, we don't call replace_mount_options (thus we don't erase existing reported options). Note that to properly report options after remount, the reiserfs filesystem should implement the show_options method. Without the show_options method, options changed with remount replace existing options. Signed-off-by:
